账号	hadoop
源路径	/opt/software/hbase-1.2.4-bin.tar.gz
目标路径	/opt/hbase -> /opt/hbase-1.2.4
依赖关系	无

2.安装过程

1).使用hadoop账号解压到/opt/hadoop目录下并设置软连接：

[root@bgs-5p173-wangwenting opt]# su hadoop

[hadoop@bgs-5p173-wangwenting opt]$ cd /opt/software

[hadoop@bgs-5p173-wangwenting software]$ tar -zxvf hbase-${version}-bin.tar.gz -C /opt

[hadoop@bgs-5p173-wangwenting software]$ cd /opt

[hadoop@bgs-5p173-wangwenting opt]$ ln -s  hbase-${version}/   hbase

2).进入/opt/hbase/conf目录,修改hbase-env.sh文件内容:

[hadoop@bgs-5p173-wangwenting opt]$ cd /opt/hbase/conf

[hadoop@bgs-5p173-wangwenting opt]$ vim hbase-env.sh

export JAVA_HOME=/opt/java

export HBASE_PID_DIR=/opt/pids

export HADOOP_HOME=/opt/hadoop

export HBASE_HOME=/opt/hbase

3).修改hbase-site.xml文件内容:

[hadoop@bgs-5p173-wangwenting opt]$ vim hbase-site.xml

添加下面内容

<configuration>

    <property>

        <name>hbase.rootdir</name>

        <value>hdfs://bgs-5p173-wangwenting:9000/hbase</value>

    </property>

    <property>

        <name>hbase.cluster.distributed</name>

        <value>true</value>

    </property>

    <property>

        <name>hbase.zookeeper.quorum</name>

        <value>bgs-5p173-wangwenting,bgs-5p174-wangwenting,bgs-5p175-wangwenting</value>

    </property>

</configuration>

4).修改/opt/hadoop/hbase/conf/regionservers文件内容:

[hadoop@bgs-5p173-wangwenting opt]$ vim /opt/hbase/conf/regionservers

添加以下内容：

bgs-5p174-wangwenting

bgs-5p175-wangwenting

5).通过scp复制到其它两台机器上:

[hadoop@bgs-5p173-wangwenting opt]$ scp -r /opt/hbase-${version} hadoop@bgs-5p174-wangwenting:/opt

[hadoop@bgs-5p174-wangwenting opt]$ ln -s hbase-${version}/  hbase

[hadoop@bgs-5p173-wangwenting opt]$ scp -r /opt/hbase-${version} hadoop@bgs-5p175-wangwenting:/opt

[hadoop@bgs-5p175-wangwenting opt]$ ln -s hbase-${version}/  hbase

6).在bgs-5p173-wangwenting上启动hbase集群:

[hadoop@bgs-5p173-wangwenting opt]$ /opt/hbase/bin/start-hbase.sh

7).查看集群是否启动，运行jps

[hadoop@bgs-5p173-wangwenting opt]$ jps

若bgs-5p173-wangwenting如下所示：

22898 ResourceManager

20739 Jps

24383 JobHistoryServer

20286 HMaster

22722 SecondaryNameNode

22488 NameNode

[hadoop@bgs-5p174-wangwenting opt]$ jps

2141 NodeManager

3257 HRegionServer

25283 Jps

1841 DataNode

[hadoop@bgs-5p175-wangwenting opt]$ jps

2141 NodeManager

3257 HRegionServer

25283 Jps

1841 DataNode

显示有HMaster和HRegionServer,则说明启动成功

8).使用/opt/hadoop/hbase/bin/hbase shell命令测试安装结果:

[hadoop@bgs-5p173-wangwenting opt]$ /opt/hbase/bin/hbase shell

a.创建表test:

hbase(main):002:0> create "test", "cf"

0 row(s) in 2.5840 seconds

=> Hbase::Table - test

b.列出全部表:

hbase(main):003:0> list

TABLE                                                                                                              

test                      

1 row(s) in 0.0310 seconds

=> ["test"]

如果在输入list,有好几次，启动Hadoop和HBase之后，执行jps命令，已经看到有HMaster的进程，但是进入到HBase的shell，执行一个命令，会出现下面的错误：

解决方法：

进入到logs目录查看master的日志：发现一直显示下面的内容：

vim hbase-hadoop-master-s1.log

2017-03-13 17:13:17,374 INFO org.apache.hadoop.hbase.util.FSUtils: Waiting for dfs to exit safe mode...
2017-03-13 17:13:27,377 INFO org.apache.hadoop.hbase.util.FSUtils: Waiting for dfs to exit safe mode...
2017-03-13 17:13:37,386 INFO org.apache.hadoop.hbase.util.FSUtils: Waiting for dfs to exit safe mode...
2017-03-13 17:13:47,393 INFO org.apache.hadoop.hbase.util.FSUtils: Waiting for dfs to exit safe mode...
2017-03-13 17:13:57,395 INFO org.apache.hadoop.hbase.util.FSUtils: Waiting for dfs to exit safe mode...
2017-03-13 17:14:07,409 INFO org.apache.hadoop.hbase.util.FSUtils: Waiting for dfs to exit safe mode...

原来是Hadoop在刚启动的时候，还处在安全模式造成的,手动退出Hadoop的安全模式.然后重新启动hbase服务。

重启后输入list，便不再报错了。

c.插入数据到test表:

hbase(main):001:0> put "test","row","cf:a","value"

0 row(s) in 0.4150 seconds

d.查看test表信息:

hbase(main):002:0> scan 'test'

ROW           COLUMN+CELL                                                                         

row          column=cf:a, timestamp=1447246157917, value=value                                   

1 row(s) in 0.0270 seconds

若hbase shell测试成功，则进入浏览器访问以下网址:http://172.24.5.173:16010/，

若正常显示，则hbase集群安装成功!  用ip保险一点，用域名首先要在自己的电脑host文件中配置。

9).启动thriftserver2服务

[hadoop@bgs-5p173-wangwenting opt]$ nohup /opt/hbase/bin/hbase-daemon.sh start thrift2 &
