基于Hadoop集群的HBase集群的配置
1.准备工作
a.已经完成安装的Hadoop集群环境
b.所需要的软件包
zookeeper-3.4.4.tar.gz下载地址：
http://downloads.gotsoft.com/pub/apache/zookeeper/zookeeper-3.4.4/
hbase-0.94.6.1tar.gz下载地址：
http://labs.mop.com/apache-mirror/hbase/stable/hbase-0.94.6.1.tar.gz
2.单独安装的ZooKeeper集群，不基于Hbase集群管理
a.在Master节点上解压zookeeper
l ##建议使用hduser权限，避免之后出现SSH错误
hduser@master:/usr/local$sudo tar -zxvfzookeeper-3.4.4.tar.gz
l ##server后面的数字是zooKeeper识别时后的Id，需要与后面的设置保持一致
hduser@master:/usr/local$tvi /zookeeper/conf/zoo.cfg
tickTime=2000
initLimit=5
syncLimit=2
dataDir=/data/zookeeper
clientPort=2181
server.1=master:2888:3888
server.2=slave1:2888:3888
server.3=slave2:2888:3888
root@master:/usr/local# chown -Rhduser:hadoop zookeeper
3.将zookeeper复制到其他机器
hduser@master:/usr/local$scp -r zookeeper-3.4.5hduser@slave1:/home/hduser
hduser@master:/usr/local$ scp -rzookeeper-3.4.5 hduser@slave2:/home/hduser
hduser@slave1:~#sudomv zookeeper-3.4.5/ /usr/local/zookeeper-3.4.5
hduser@slave2:~$sudomv zookeeper-3.4.5/ /usr/local/zookeeper-3.4.5
4.在每台机器配置的dataDir目录下面，创建myid文件标志当前主机
Master： $touch /data/zookeeper/myid
$echo "1" >/data/zookeeper/myid
Slave1： $mkdir -p /data/zookeeper
$touch /data/zookeeper/myid
$echo "3" > /data/zookeeper/myid
Slave2: $mkdir -p/data/zookeeper
$touch /data/zookeeper/myid
$echo "5" > /data/zookeeper/myid
5. 启动zookeeper集群
hduser@master:/usr/local/zookeeper/bin$./zkServer.sh start
JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
【问题1】Starting zookeeper ... ./zkServer.sh: line 113:/data/zookeeper/zookeeper_server.pid: Permission denied
FAILED TO WRITE PID
原因是刚才/data/zookeeper是root权限，而不是hduser的，修改权限之~
【问题1解决】root@master:/# chown -Rhduser:hadoop /data
其他两个slave节点也一样~
然后问题解决：
hduser@master:/usr/local/zookeeper$ cd bin
hduser@master:/usr/local/zookeeper/bin$ ./zkServer.sh start
JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED
其他节点也同样启动zookeeper~
hduser@master:/usr/local/zookeeper/bin$
hduser@slave1:/usr/local/zookeeper/bin$./zkServer.sh status
JMX enabled by default
Using config: /usr/local/zookeeper/bin/../conf/zoo.cfg
【问题2】Error contacting service. It is probably notrunning.
1）查看zoopkeeper.out

【错误2解决】没有将zookeeper复制到其他的节点！！！
没有在每个节点启动zookeeper
6.安装配置Hbase集群
a>启动HDFS集群实例,并创建目录
##hdfs://master01:54310/hbase【注意与hadoop，core-site.xml中的fs.default.name中的端口号保持一致，统一设置为54310；hbase-site.xml中的hbase:rootdir中的端口号】
hduser@master:/usr/local/hadoop$bin/hadoop fs -mkdir /hbase
Warning: $HADOOP_HOME is deprecated.

HBASE SHELL 错误NativeException: org.apache.hadoop.hbase.MasterNotRunningException:null
【解决步骤：】
1、启动hadoop后，需要等一段时间，再开启hbase
2、去掉hadoop的安全模式：
hadoop dfsadmin -safemode leave
3、把/etc/hosts里的master01的IP改为服务器当前的IP
4、确认hbase的hbase-site.xml中
<name>hbase.rootdir</name>
<value>hdfs://localhost:8020/hbase</value>
与hadoop的core-site.xml中
<name>fs.default.name</name>
<value>hdfs://localhost:8020</value>
红字部分保持一致
5、确认hadoop版本是0.20.2，hbase版本是0.20.6
6、重新执行./start-hbase.sh之前，先kill掉当前的hbase和zookeeper进程
之后再执行：
$bin/hadoop fs -mkdir /hbase
b> 解压hbase-0.94.5.tar.gz，修改配置文件，正式安装HBase：
l #vi hbase-0.94.5/conf/hbase-env.sh
exportJAVA_HOME=/usr/java/jdk1.6.0_43
exportHBASE_CLASSPATH=$HBASE_HOME/
#exportHBASE_HEAPSIZE=128
#exportHBASE_OPTS="-XX:+UseConcMarkSweepGC"
exportHBASE_MANAGES_ZK=false
#vi hbase-0.94.5/conf/regionservers
slave1
slave2
l 将hbase-webapps目录改名为webapps
hduser@master:/usr/local/hbase-0.94.6$ mvhbase-webapps/ /webapps
l 检查HBase配置，复制到其他的slave节点：
hduser@master:/usr/local$ scp -rhbase-0.94.6 hduser@slave1:/home/hduser/
hduser@master:/usr/local$ scp -rhbase-0.94.6 hduser@slave2:/home/hduser/
l 启动HBase：
hduser@master:/usr/local$ ./hbase-0.94.6/bin/start-hbase.sh
starting master, logging to/usr/local/hbase-0.94.6/bin/../logs/hbase-hduser-master-master.out
slave2: starting regionserver, logging to/usr/local/hbase-0.94.6/bin/../logs/hbase-hduser-regionserver-slave2.out
slave1: starting regionserver, logging to/usr/local/hbase-0.94.6/bin/../logs/hbase-hduser-regionserver-slave1.out
l 查看相关进程：

【错误】13/04/27 05:47:21ERROR client.HConnectionManager$HConnectionImplementation: Check the valueconfigured in 'zookeeper.znode.parent'. There could be a mismatch with the oneconfigured in the master.
l 去掉hadoop的安全模式
hduser@master:/usr/local/hadoop$ bin/hadoopdfsadmin -safemode leave
Warning: $HADOOP_HOME is deprecated.
