这篇文章给大家分享的是有关hbase-1.1.3基于hadoop-2.6.2 ha分布式部署的示例分析的内容。小编觉得挺实用的,因此分享给大家做个参考,一起跟随小编过来看看吧。
集群说明
hadoop-2.5.2采用ha方式部署,所有namenode是hdfs://masters,zookeeper地址:bi3:2181,bi4:2181,bi5:2181
IP | 主机名 | 部署 |
192.168.2.10 | bi10 | hadoop-2.6.2,HMaster,HRegionServer |
192.168.2.12 | bi12 | hadoop-2.6.2,HMaster,HRegionServer |
192.168.2.13 | bi13 | hadoop-2.6.2 |
Hbase-1.1.3部署
解压habse-1.1.3到/home/hadoop/work/hbase-1.1.3
修改conf/hbase-env.sh,需要HBASE_CLASSPATH=hadoop配置文件位置,否则hbase不能识别hdfs://masters/hbase这种namenode ha的配置方式。
# The java implementation to use. Java 1.7+ required.
export JAVA_HOME=/home/hadoop/work/jdk1.7.0_75
# Extra Java CLASSPATH elements. Optional.
export HBASE_CLASSPATH=/home/hadoop/work/hadoop-2.6.2/etc/hadoop
# Tell HBase whether it should manage it's own instance of Zookeeper or not.
export HBASE_MANAGES_ZK=false
修改conf/hbase-site.xml
<configuration>
<property>
<name>hbase.rootdir</name>
<value>hdfs://masters/hbase</value>
</property>
<property>
<name>hbase.cluster.distributed</name>

</property>
<property>
<name>hbase.master</name>
<value>60000</value>

<property>
<name>hbase.zookeeper.quorum</name>
<value>bi3:2181,bi4:2181,bi5:2181</value>

<property>

<value>/home/hadoop/work/hbase-1.1.3/zookeeper/</value>
</property>
<property>
<name>hbase.tmp.dir</name>
<value>/home/hadoop/work/hbase-1.1.3/tmp/</value>
</property>
</configuration>
修改conf/regionservers
bi10
bi12
修改~/.bash_profile,增加环境变量
#init hbase_environment
export HBASE_HOME=/home/hadoop/work/hbase-1.1.3
export PATH=$PATH:$HBASE_HOME/bin
启动habse
在bi10上启动habse
[hadoop@bi10 hbase-1.1.3]$ start-hbase.sh
starting master, logging to /home/hadoop/work/hbase-1.1.3/logs/hbase-hadoop-master-bi10.out
bi12: starting regionserver, logging to /home/hadoop/work/hbase-1.1.3/bin/../logs/hbase-hadoop-regionserver-bi12.out
bi10: starting regionserver, logging to /home/hadoop/work/hbase-1.1.3/bin/../logs/hbase-hadoop-regionserver-bi10.out
在bi12上启动另一个HMaster
[hadoop@bi12 hbase-1.1.3]$ hbase-daemon.sh start master
starting master, logging to /home/hadoop/work/hbase-1.1.3/logs/hbase-hadoop-master-bi12.out
看下进程,两台主机都应该有HRegionServer,HMaster就对了
