不多说，直接上干货！
我的集群机器情况是 bigdatamaster（192.168.80.10）、bigdataslave1（192.168.80.11）和bigdataslave2（192.168.80.12）
然后，安装目录是在/home/hadoop/app下。
官方建议在master机器上安装Hue，我这里也不例外。安装在bigdatamaster机器上。
Hue版本：hue-3.9.0-cdh5.5.4
需要编译才能使用（联网） 说给大家的话：大家电脑的配置好的话，一定要安装cloudera manager。毕竟是一家人的。
同时，我也亲身经历过，会有部分组件版本出现问题安装起来要个大半天时间去排除，做好心里准备。废话不多说，因为我目前读研，自己笔记本电脑最大8G，只能玩手动来练手。
纯粹是为了给身边没高配且条件有限的学生党看的！ 但我已经在实验室机器群里搭建好cloudera manager 以及 ambari都有。
大数据领域两大最主流集群管理工具Ambari和Cloudera Manger

Ambari安装搭建部署大数据集群（图文分五大步详解）（博主强烈推荐）
问题一：
1、HUE中Hive 查询有问题，页面报错：Could not connect to localhost:10000 或者 Could not connect to bigdatamaster:10000
解决方法：
在安装的HIVE中启动hiveserver2 &,因为端口号10000是hiveserver2服务的端口号，否则，Hue Web 控制无法执行HIVE 查询。
bigdatamaster是我机器名。
在$HIVE_HOME下
bin/hive -–service hiveserver2 &
[hadoop@bigdatamaster ~]$ cd $HIVE_HOME
[hadoop@bigdatamaster hive]$ bin/hive --service hiveserver2 &
大家，注意，以下是我的hive-site.xml里的配置信息
该问题，成功解决。
问题二：
database is locked
这应该是hue默认的SQLite数据库出现错误，你可以使用mysql postgresql等来替换
https://www.cloudera.com/documentation/enterprise/5-5-x/topics/admin_hue_ext_db.html（这是官网）
同时，参考（见https://my.oschina.net/aibati2008/blog/647493）
这篇博客：安装配置和使用hue遇到的问题汇总
# Configuration options for specifying the Desktop Database. For more info,
# see http://docs.djangoproject.com/en/1.4/ref/settings/#database-engine
# ------------------------------------------------------------------------
[[database]]
# Database engine is typically one of:
# postgresql_psycopg2, mysql, sqlite3 or oracle.
#
# Note that for sqlite3, 'name', below is a path to the filename. For other backends, it is the database name.
# Note for Oracle, options={"threaded":true} must be set in order to avoid crashes.
# Note for Oracle, you can use the Oracle Service Name by setting "port=0" and then "name=<host>:<port>/<service_name>".
# Note for MariaDB use the 'mysql' engine.
## engine=sqlite3
## host=
## port=
## user=
## password=
## name=desktop/desktop.db
## options={}
以上是默认的。
hue默认使用sqlite作为元数据库，不推荐在生产环境中使用。会经常出现database is lock的问题。
解决方法：
其实官网也有解决方法，不过过程似乎有点问题。而且并不适合3.7之后的版本。我现在使用的是3.11，以下是总结的最快的切换方法。

因为，我这里是，用户为hive，密码也为hive，然后，数据库也为hive，所以如下：

然后，重启hue进程
[hadoop@bigdatamaster hue]$ build/env/bin/supervisor
完成以上的这个配置，启动Hue,通过浏览器访问，会发生错误，原因是mysql数据库没有被初始化
DatabaseError: (1146, "Table 'hue.desktop_settings' doesn't exist")
或者
ProgrammingError: (, "Table 'hive.django_session' doesn't exist")
初始化数据库
/home/hadoop/app/hue-3.9.-cdh5.5.4/build/env
bin/hue syncdb
bin/hue migrate执行完以后，可以在mysql中看到，hue相应的表已经生成。
启动hue, 能够正常访问了。
或者
当然，大家这里，可以先在mysql里面创建数据库。命名为hue，并且是以hadoop用户和hadoop密码。
首先，
[root@master app]# mysql -uroot -prootroot
mysql> create user 'hue' identified by 'hue'; //创建一个账号：用户名为hue，密码为hue
或者
mysql> create user 'hue'@'%' identified by 'hue'; //创建一个账号：用户名为hue，密码为hue
mysql> GRANT ALL PRIVILEGES ON *.* to 'hue'@'%' IDENTIFIED BY 'hue' WITH GRANT OPTION; //将权限授予host为%即所有主机的hue用户
mysql> GRANT ALL PRIVILEGES ON *.* to 'hue'@'bigdatamaster' IDENTIFIED BY 'hue' WITH GRANT OPTION; //将权限授予host为master的hue用户
mysql> GRANT ALL PRIVILEGES ON *.* to 'hue'@'localhost' IDENTIFIED BY 'hue' WITH GRANT OPTION; //将权限授予host为localhost的hue用户（其实这一步可以不配）
mysql> GRANT ALL PRIVILEGES ON *.* to 'hue'@'bigdatamaster' IDENTIFIED BY 'hue' WITH GRANT OPTION;

启动hue之后，比如如下的错误，原因是mysql数据库没有被初始化。
ProgrammingError: (, "Table 'hue.django_session' doesn't exist")
则初始化数据库
cd /home/hadoop/app/hue-3.9.0-cdh5.5.4/build/env
bin/hue syncdb
bin/hue migrate
具体如下（这里一定要注意啦！！！先看完，再动手）
这里，大家一定要注意啊，如果这里你输入的是默认提示hadoop，则在登录的时候就是为hadoop啦。
当然若这里，大家弄错了的话，还可以如我下面这样进行来弥补。
第一步：
所以，这样下来，不太好。
所以我这里，为了避免这个情况发生，直接输入用户名为hue，密码也是为hue。

问题三：
Error loading MySQLdb module: libmysqlclient_r.so.16: cannot open shared object file: No such file or directory
解决办法
把安装mysql 的虚拟机里找一个直接把libmysqlclient.so.18这个文件拷贝到系统指定的/usr/lib64库文件目录中。
大家，注意，以下是我的hive-site.xml配置信息，我的hive是安在bigdatamaster机器上，
我的这里配置是，
# Database options to send to the server when connecting.
# https://docs.djangoproject.com/en/1.4/ref/databases/
## options={} # mysql, oracle, or postgresql configuration.
[[[mysql]]]
# Name to show in the UI.
nice_name="My SQL DB" # For MySQL and PostgreSQL, name is the name of the database.
# For Oracle, Name is instance of the Oracle server. For express edition
# this is 'xe' by default.
name=hive # Database backend to use. This can be:
# . mysql
# . postgresql
# . oracle
engine=mysql # IP or hostname of the database to connect to.
host=bigdatamaster # Port the database server is listening to. Defaults are:
# . MySQL:
# . PostgreSQL:
# . Oracle Express Edition:
port= # Username to authenticate with when connecting to the database.
user=hive # Password matching the username to authenticate with when
# connecting to the database.
password=hive # Database options to send to the server when connecting.
# https://docs.djangoproject.com/en/1.4/ref/databases/
## options={}
该问题成功得到解决！
问题四（跟博文的问题十五一样）
点击“File Browser”报错：
Cannot access:/user/admin."注：您是hue管理员，但不是HDFS超级用户（即“”HDFS“”）
解决方法：
在$HADOOP_HOME的etc/hadoop中编辑core-site.xml文件,增加
<property>
<name>hadoop.proxyuser.oozie.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.ozzie.groups</name>
<value>*</value>
</property> <property>
<name>hadoop.proxyuser.hue.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hue.groups</name>
<value>*</value>
</property>
然后重启hadoop，stop-all.sh----->start-all.sh即可。
该问题成功得到解决!
我一般配置是如下，在$HADOOP_HOME/etc/hadoop/下的core-site.xml里
<property>
<name>hadoop.proxyuser.hadoop.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hadoop.groups</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hue.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hue.groups</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hdfs.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hdfs.groups</name>
<value>*</value>
</property>
为什么要这么加，是因为，我有三个用户，
这里，大家根据自己的实情去增加，修改完之后，一定要重启sbin/start-all.sh，就能解决问题了。
问题五
在Hue对HBase集成时， HBase Browser 里出现 Api Error: TSocket read 0 bytes
解决办法
https://*.com/questions/20415493/api-error-tsocket-read-0-bytes-when-using-hue-with-hbase
Add this to your hbase "core-site.conf":
<property>
<name>hbase.thrift.support.proxyuser</name>
<value>true</value>
</property>
<property>
<name>hbase.regionserver.thrift.http</name>
<value>true</value>
</property>
即可，解决问题。
问题六：

解决办法
$HADOOP_HOME/ect/hadoop的core-site.xml里
<property>
<name>hadoop.proxyuser.hue.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hue.groups</name>
<value>*</value>
</property>
改为
<property>
<name>hadoop.proxyuser.hue.hosts</name>
<value>hadoop</value>
</property>
<property>
<name>hadoop.proxyuser.hue.groups</name>
<value>hadoop</value>
</property>
问题七
Api 错误：集群配置 (Cluster|bigdatamaster:9090 的格式设置不正确。
改为
问题八：
在hue里面查看HDFS文件浏览器报错:
当前用户没有权限查看,
cause:org.apache.hadoop.ipc.StandbyException: Operation category READ is not supported in state standby
解决方案:
Web页面查看两个NameNode状态，是不是之前的namenode是standby状态了. 我现有的集群就是这种情况, 由于之前的服务是master1起的, 挂了之后自动切换到master2, 但是hue中webhdfs还是配置的master1,导致在hue中没有访问权限.
问题九
hive查询时报错
org.apache.hive.service.cli.HiveSQLException: Couldn't find log associated with operation handle: OperationHandle [opType=EXECUTE_STATEMENT, getHandleIdentifier()=b3d05ca6-e3e8-4bef-b869-0ea0732c3ac5]
解决方案:
将hive-site.xml中的hive.server2.logging.operation.enabled=true;
<property>
<name>hive.server2.logging.operation.enabled</name>
<value>true</value>
</property>
问题十
启动hue web端 报错误：OperationalError: attempt to write a readonly database
解决办法
启动hue server的用户没有权限去写入默认sqlite DB，同时确保安装目录下所有文件的owner都是hadoop用户
chown -R hadoop:hadoop hue-3.9.-cdh5.5.4
问题十一
HUE 报错误：Filesystem root ‘/’ should be owned by ‘hdfs’
hue 文件系统根目录“/”应归属于“hdfs”
解决方法
修改 文件desktop/libs/hadoop/src/hadoop/fs/webhdfs.py 中的 DEFAULT_HDFS_SUPERUSER = ‘hdfs’ 更改为你的hadoop用户
问题十二
错误：hbase-site.xml 配置文件中缺少 kerberos 主体名称。
解决办法
问题十三
Hue下无法无法正确连接到 Zookeeper timed out
解决办法
说明你的zookeeper模块，还没配置完全。
HUE配置文件hue.ini 的zookeeper模块详解（图文详解）（分HA集群）
问题十四
Sqoop 错误: 无法获取连接器。
解决办法
看下自己的sqoop版本是不是，不是Sqoop2版本。好比我的如下
大家要注意，Hue里是只支持Sqoop2版本，对于Sqoop1和Sqoop2版本，直接去官网看就得了。
那么，得更换sqoop版本。
sqoop2-1.99.5-cdh5.5.4.tar.gz的部署搭建
问题十五（见本博客的问题四）
无法访问：/user/hadoop。 Note: you are a Hue admin but not a HDFS superuser, "hdfs" or part of HDFS supergroup, "supergroup".
SecurityException: Failed to obtain user group information: org.apache.hadoop.security.authorize.AuthorizationException: User: hue is not allowed to impersonate hadoop (error 403)
问题分析
那是因为，HUE安装完成之后，第一次登录的用户就是HUE的超级用户，可以管理用户，等等。但是在用的过程发现一个问题这个用户不能管理HDFS中由supergroup创建的数据。
虽然在HUE中创建的用户可以管理自己文件夹下面的数据/user/XXX。那么Hadoop superuser的数据怎么管理呢，ＨＵＥ提供了一个功能就是将Unix的用户和Hue集成，这样用Hadoop superuser的用户登录到ＨＵＥ中就能顺利的管理数据了。
下面几个步骤来进行集成
第一步：确保hadoop 这个用户组在系统之中（这个hadoop肯定是在系统中了）
第二步：运行下面命令
[hadoop@bigdatamaster env]$ pwd
/home/hadoop/app/hue-3.9.-cdh5.5.4/build/env
[hadoop@bigdatamaster env]$ ll
total
drwxrwxr-x hadoop hadoop May : bin
drwxrwxr-x hadoop hadoop May : include
drwxrwxr-x hadoop hadoop May : lib
lrwxrwxrwx hadoop hadoop May : lib64 -> lib
drwxrwxr-x hadoop hadoop Aug : logs
-rw-rw-r-- hadoop hadoop May : stamp
[hadoop@bigdatamaster env]$ bin/hue useradmin_sync_with_unix
[hadoop@bigdatamaster env]$
第三步：
运行完上面的命令，进入到ＨＵＥ总你就会发现用户已经集成进来了，但是，没有密码，所以需要给Ｕｎｉｘ的用户设定密码和分配用户组。
这里，
或者
完成上述步骤之后，登陆进去，就能愉快地管理ＨＤＦＳ数据了。
HUE新建HDFS目录
问题描述: you are a Hue admin but not a HDFS superuser, “hdfs” or part of HDFS supergroup, “supergroup”
解决方案：在hue中新增hdfs用户，以hdfs用户登录创建目录和上传文件
参考
https://geosmart.github.io/2015/10/27/CDH%E4%BD%BF%E7%94%A8%E9%97%AE%E9%A2%98%E8%AE%B0%E5%BD%95/
然后，其实还是没有成功，
说白了，这个问题还是要看本博文的问题四
我一般配置是如下，在$HADOOP_HOME/etc/hadoop/下的core-site.xml里
<property>
<name>hadoop.proxyuser.hadoop.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hadoop.groups</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hue.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hue.groups</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hdfs.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hdfs.groups</name>
<value>*</value>
</property>
为什么要这么加，是因为，我有三个用户，
这里，大家根据自己的实情去增加，修改完之后，一定要重启sbin/start-all.sh，就能解决问题了。
问题十六
无法为用户hue创建主目录， 无法为用户hadoop创建主目录，无法为用户hdfs创建主目录。
解决办法
在$hadoop/etc/hadoop/core-site.xml
<property>
<name>hadoop.proxyuser.hue.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hue.groups</name>
<value>*</value>
</property>
比如，以下是无法为用户hdfs创建主目录，则
<property>
<name>hadoop.proxyuser.hdfs.hosts</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.hdfs.groups</name>
<value>*</value>
</property>
成功！
问题十七
User [hue] not defined as proxyuser
问题来源：
The oozie is running, when I click WorkFlows, there appares a error
即，oozie启动后，当我在hue界面点击workfolws后，出现如下的错误
解决办法
Hue submits MapReduce jobs to Oozie as the logged in user. You need to configure Oozie to accept the hue user to be a proxyuser. Specify this in your oozie-site.xml (even in a non-secure cluster), and restart Oozie:
<property>
<name>oozie.service.ProxyUserService.proxyuser.hue.hosts</name>
<value>*</value>
</property>
<property>
<name>oozie.service.ProxyUserService.proxyuser.hue.groups</name>
<value>*</value>
</property>
参考： http://archive.cloudera.com/cdh4/cdh/4/hue-2.0.0-cdh4.0.1/manual.html
即，在oozie-site.xml配置文件里，加入
添加好之后，然后重启oozie。记得先jps下进程，Kill掉，再重启。
注意：/home/hadoop/app/oozie是我安装oozie的目录。
或者执行以下命令重启也是可以的。
[hadoop@bigdatamaster oozie]$ pwd
/home/hadoop/app/oozie
[hadoop@bigdatamaster oozie]$ bin/oozied.sh restart
然后，得到
问题十八
Oozie 服务器未运行
解决办法
Oozie的详细启动步骤（CDH版本的3节点集群）
问题十九
Api 错误：('Connection aborted.', error(111, 'Connection refused'))
解决办法
问题二十
Could not connect to bigdatamaster:21050
解决办法
开启impala服务
问题二十一：
OperationalError: (2003, "Can't connect to MySQL server on 'bigdatamaster' (111)")
解决办法
[root@bigdatamaster hadoop]# service mysqld start
Starting mysqld: [ OK ]
[root@bigdatamaster hadoop]#
再刷新即可。
问题二十二： Hue执行./build/env/bin/supervisor出现
IOError: [Errno 13] Permission denied: '/opt/modules/hue-3.9.0-cdh5.5.0/logs/supervisor.log
File "./build/env/bin/supervisor", line 9

IOError: [Errno ] Permission denied: '/opt/modules/hue-3.9.0-cdh5.5.0/logs/supervisor.log'
解决办法：
只有build是root权限，其他都是普通用户。
问题二十三: 当前没有已配置的数据库。请转到您的 Hue 配置并在“rdbms”部分下方添加数据库。
以下是，默认的
###########################################################################

再，停掉mysql，重启mysql和hue

即，Hue的服务器（名字为My SQL DB，一般是mysql, oracle, or postgresql）。通常用mysql。
那么，它的数据库是metastore，是在hive里新建的mysql来充当它的元数据库。
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://master:3306/metastore?createDatabaseIfNotExist=true</value>
</property>
Hue的服务器（名字为SQLite），那么它的数据库是/opt/modules/hue-3.9.0-cdh5.5.0/desktop/desktop.db
问题二十四: hue HBase Thrift 1 server cannot be contacted: 9090
问题二十五:
Api Error: Invalid method name: 'getTableNames'
产生的原因
后来通过查询资料，怀疑是客户端thrift版本和hbase thrift server的thrift版本不一致造成的。
果然thrift server上是使用的thrift2启动的，而客户端使用的是thrift访问的。
解决方法
因为根本原因在于客户端和服务器thrift版本不一致，那么解决方法有两个：
服务端以启动thrift版本的thrift server
hbase 的 thrift server以thrift1方式启动。
# hbase-daemon.sh stop thrift2 #启动命令 hbase-daemon.sh start thrift
问题二十六:
socket.error: [Errno 98] Address already in use 出现这个问题的原因是：
在于，当hue还在运行，你也许在命令行里进行了如hue.ini的修改，然后没正常关闭Hue再开启。
问题二十七:
二十八
desktop_settings' doesn't exist
然后，重启hue进程
[hadoop@bigdatamaster hue]$ build/env/bin/supervisor
完成以上的这个配置，启动Hue,通过浏览器访问，会发生错误，原因是mysql数据库没有被初始化
DatabaseError: (1146, "Table 'hue.desktop_settings' doesn't exist")
或者
ProgrammingError: (1146, "Table 'hive.django_session' doesn't exist")
初始化数据库
/home/hadoop/app/hue-3.9.0-cdh5.5.4/build/env
bin/hue syncdb
bin/hue migrate执行完以后，可以在mysql中看到，hue相应的表已经生成。
启动hue, 能够正常访问了。
二十九：
build/env/bin/supervisor 执行时，出现 No such file or diretory
解决办法：
如果你实在不会安装，或者说搞不定安装Hue，则就去别人机器上拷贝一个已经安装好的Hue。
放心，是可以放到你的Apache集群或者CDH集群里的，作者亲身经历过。
只是，需要自己手动，将软连接重新做一遍，这个不难的，删除，再重新ln -s 即可嘛。
三十 Hue界面登录的密码忘记了？？
如我刚开始，用户是hadoop，密码也是hadoop。 现在，我想改为hue，密码也是hue。
此时，用户名是由hadoop，改为hue了，但是密码还没改过来，别急。
