1、環境介紹
（1）IP 規劃
hserver 192.168.0.130
hclient1 192.168.0.131
hclient2 192.168.0.132
（2）軟件版本
OS：rhel6.3-x86_64
JDK：jdk1.6.0_41
HADOOP：hadoop-1.1.1
HBASE：hbase-0.94.5
2、Hbase安裝
下載地址：http://mirror.bit.edu.cn/apache/hbase/hbase-0.94.5/hbase-0.94.5.tar.gz
解壓安裝：$tar zvxf hbase-0.94.5.tar.gz
hadoop安裝目錄：/hadoop/hadoop-1.1.1
hbase安裝目錄：/hadoop/hbase-0.94.5
3、Hbase配置
（1）$vim hbase-env.sh
export JAVA_HOME=/hadoop/jdk1.6.0_41
export HBASE_CLASSPATH=/hadoop/hadoop-1.1.1
export HBASE_MANAGES_ZK=true
（2）$vim hbase-site.xml
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://hserver:9000/hadoop/hbase</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>hserver,hclient1,hclient2</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/hadoop/zookeeper</value>
</property>
</configuration>
（3）$vim regionservers
hclient1
hclient2
4、Hbase啓停
注意啓動順序：保證Hadoop已經正常啓動後，啓動 Hbase
啓動：$/bin/start-hbases
（1）server端jps查看進程
$jps
9800 Jps
4389 JobTracker
4116 NameNode
4297 SecondaryNameNode
9488 HQuorumPeer
9611 HMaster
（2）slave端jps查看進程
$jps
5359 Jps
2784 DataNode
5190 HRegionServer
2894 TaskTracker
5041 HQuorumPeer
5、Hbase 操作
（1）Web 方式
Hbase Master 訪問地址 http://hserver:60010
Region Server 訪問地址 http://hclient1:60030
（2）Shell 方式
$ hbase shell
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell

1 row(s) in 0.0150 seconds
//禁用表：disable '表名稱'
hbase(main):022:0> disable 'user'
0 row(s) in 2.0710 seconds
//刪除表：drop '表名稱'
hbase(main):023:0> drop 'user'
0 row(s) in 1.0490 seconds
hbase(main):024:0> list
TABLE
0 row(s) in 0.0090 seconds
6、遇到的問題：
（1）jps查看slave節點，HRegionServer進程未啓動，hbase-hadoop-regionserver-hclient1.log日誌報錯
FATAL org.apache.hadoop.hbase.regionserver.HRegionServer: Master rejected startup because clock is out of sync
org.apache.hadoop.hbase.ClockOutOfSyncException: org.apache.hadoop.hbase.ClockOutOfSyncException: Server hclient1,60020,1362557838693 has been rejected; Reported time is too far out of sync with master. Time difference of 43200339ms > max allowed of 30000ms
原因：時鐘不同步
