HBase完全分布模式安装(2)

[grid@gc conf]$ vi hbase-site.xml

# 添加如下内容

<property>

<name>hbase.rootdir</name> #设置hbase数据库存放数据的目录

<value>hdfs://gc:9000/hbase</value>

</property>

<property>

<name>hbase.cluster.distributed</name>  #打开hbase分布模式

<value>true</value>

</property>

<property>

<name>hbase.master</name> #指定hbase集群主控节点

<value>gc:60000</value>

</property>

<property>

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

<value>gc,rac1,rac2</value> #指定zookeeper集群节点名,因为是由zookeeper表决算法决定的

</property>

<property>

<name>hbase.zookeeper.property.dataDir</name> #指zookeeper集群data目录

<value>/home/grid/hbase-0.90.5/zookeeper</value>

</property>

6.      编辑regionservers文件

[grid@gc conf]$ cat regionservers

# 把localhost改为如下

rac1

rac2

7.      将修改的hbase目录同步其它节点

--分别同步到rac1,rac2两节点

[grid@gc ~]$ scp -r hbase-0.90.5 rac1:/home/grid/

[grid@gc ~]$ scp -r hbase-0.90.5 rac2:/home/grid/

8.      启动/关闭Hbase数据库集群

--启动hbase之前必需检查Hadoop是否已经启动

[grid@gc ~]$ hadoop-0.20.2/bin/hadoop dfsadmin -report
