HBase 集群搭建

集群架构：

Node Name	Master	ZooKeeper	RegionServer
192.168.50.173	yes	yes	yes
192.168.50.196	backup	yes	yes
192.168.50.169	no	yes	yes

参照http://www.cnblogs.com/yanpengfei/articles/3770497.html 运行Hadoop 以及Zookeeper

下载hbase-0.98.6-hadoop2-bin.tar.gz

tar xzvf hbase-0.98.6-hadoop2-bin.tar.gz 
cd hbase-0.98.6-hadoop2

配置conf/hbase-env.sh

export JAVA_HOME=/usr/java/jdk1.7.0_60
# Tell HBase whether it should manage it's own instance of Zookeeper or not.
export HBASE_MANAGES_ZK=false

配置conf/hbase-site.xml

<property>
<name>hbase.rootdir</name>
<value>hdfs://mycluster/hbase</value>
</property>   
<property>
<name>hbase.cluster.distributed</name>
<value>true</value>

<property>
<name>hbase.master.wait.on.regionservers.mintostart</name>
<value>3</value>

<value>192.168.50.173,192.168.50.196,192.168.50.169</value>  
</property>  

 配置conf/regionservers

192.168.50.173
192.168.50.196
192.168.50.169

配置backup-masters

touch conf/backup-masters
添加新行192.168.50.196

scp -r hbase-0.98.6-hadoop2 192.168.50.196:/home/hadoop/app/
scp -r hbase-0.98.6-hadoop2 192.168.50.169:/home/hadoop/app/

HBase配置完毕。
