1.基本信息

版本安裝機器賬號源路徑目標路徑依賴關系

1.2.4

三臺機器

hadoop

/opt/software/hbase-1.2.4-bin.tar.gz

/opt/hbase?->?/opt/hbase-1.2.4

無

2.安裝過程

1).使用hadoop賬號解壓到/opt/hadoop目錄下并設置軟連接：

[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).進入/opt/hbase/conf目錄,修改hbase-env.sh文件內容:

[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文件內容:

[hadoop@bgs-5p173-wangwenting opt]$ vim hbase-site.xml 添加下面內容 <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文件內容:?

[hadoop@bgs-5p173-wangwenting opt]$ vim /opt/hbase/conf/regionservers 添加以下內容： bgs-5p174-wangwenting bgs-5p175-wangwenting

5).通過scp復制到其它兩臺機器上:

[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上啟動hbase集群:

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

7).查看集群是否啟動，運行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 顯示有HMaster和HRegionServer,則說明啟動成功

8).使用/opt/hadoop/hbase/bin/hbase shell命令測試安裝結果:

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

a.創建表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"]

?如果在輸入list,有好幾次，啟動Hadoop和HBase之后，執行jps命令，已經看到有HMaster的進程，但是進入到HBase的shell，執行一個命令，會出現下面的錯誤：

解決方法：

進入到logs目錄查看master的日志：發現一直顯示下面的內容：

?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...

原來是Hadoop在剛啟動的時候，還處在安全模式造成的,手動退出Hadoop的安全模式.然后重新啟動hbase服務。

重啟后輸入list，便不再報錯了。

?

c.插入數據到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測試成功，則進入瀏覽器訪問以下網址:http://172.24.5.173:16010/，

?

若正常顯示，則hbase集群安裝成功!??用ip保險一點，用域名首先要在自己的電腦host文件中配置。

9).啟動thriftserver2服務

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