手动安装cloudera cdh4.2 hadoop + hbase + hive（三）

本文主要记录手动安装cloudera Hive cdh4.2.0集群过程，环境设置及Hadoop、HBase安装过程见上篇文章。

安装hive

hive安装在desktop1上，注意hive默认是使用derby数据库保存元数据，这里替换为postgresql，下面会提到postgresql的安装说明，并且需要拷贝postgres的jdbc jar文件导hive的lib目录下。

上传文件

上传hive-0.10.0-cdh4.2.0.tar到desktop1的/opt，并解压缩

安装postgres

创建数据库

这里创建数据库metastore并创建hiveuser用户，其密码为redhat。

psql -U postgres

CREATE DATABASE metastore;
 \c metastore;
CREATE USER hiveuser WITH PASSWORD 'redhat';
GRANT ALL ON DATABASE metastore TO hiveuser;
\q

初始化数据库

psql  -U hiveuser -d metastore
 \i /opt/hive-0.10.0-cdh4.2.0/scripts/metastore/upgrade/postgres/hive-schema-0.10.0.postgres.sql

编辑postgresql配置文件，修改访问权限

[root@desktop1 ~]# vi /opt/PostgreSQL/9.1/data/pg_hba.conf

# IPv4 local connections:
host    all             all             0.0.0.0/0            md5

[root@desktop1 ~]# vi postgresql.conf

standard_conforming_strings = off

重起postgres

su -c '/opt/PostgreSQL/9.1/bin/pg_ctl -D /opt/PostgreSQL/9.1/data restart' postgres

拷贝postgres 的jdbc驱动到/opt/hive-0.10.0-cdh4.2.0/lib

修改配置文件

hive-site.xml 注意修改下面配置文件中postgres数据库的密码，注意配置hive.aux.jars.path，在hive集成hbase时候需要从该路径家在hbase的一些jar文件。

[root@desktop1 ~]# cd /opt/hive-0.10.0-cdh4.2.0/conf/
[root@desktop1 conf]# cat hive-site.xml

环境变量

参考hadoop中环境变量的设置

启动脚本

在启动完之后，执行一些sql语句可能会提示错误，如何解决错误可以参考Hive安装与配置。

[root@desktop1 ~] hive

hive与hbase集成在hive-site.xml中配置hive.aux.jars.path,在环境变量中配置hadoop、mapreduce的环境变量

异常说明

FAILED: Error in metadata: MetaException(message:org.apache.hadoop.hbase.ZooKeeperConnectionException: An error is preventing HBase from connecting to ZooKeeper

原因：hadoop配置文件没有zk

FAILED: Error in metadata: MetaException(message:Got exception: org.apache.hadoop.hive.metastore.api.MetaException javax.jdo.JDODataStoreException: Error executing JDOQL query "SELECT "THIS"."TBL_NAME" AS NUCORDER0 FROM "TBLS" "THIS" LEFT OUTER JOIN "DBS" "THIS_DATABASE_NAME" ON "THIS"."DB_ID" = "THIS_DATABASE_NAME"."DB_ID" WHERE "THIS_DATABASE_NAME"."NAME" = ?

hive> select count(*) from hive_userinfo; 没反应
zookeeper.ClientCnxn (ClientCnxn.java:logStartConnect(966)) - Opening socket connection to server localhost/127.0.0.1:2181. Will not attempt to authenticate using SASL (无法定位登录配置)

原因：hive中没有设置zk

hbase 中提示：WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

原因：cloudera hadoop lib中没有hadoop的native jar

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/mapreduce/v2/app/MRAppMaster

原因：classpath没有配置正确，检查环境变量以及yarn的classpath
