HBase第一章 安装 HMaster 主备

1、集群环境

　　

　　Hadoop HA 集群规划

　　hadoop1 cluster1 nameNode  HMaster
　　hadoop2 cluster1 nameNodeStandby ZooKeeper ResourceManager HMaster
　　hadoop3 cluster2 nameNode              ZooKeeper
　　hadoop4 cluster2 nameNodeStandby ZooKeeper ResourceManagerStandBy
　　hadoop5 DataNode   NodeManager HRegionServer
　　hadoop6 DataNode   NodeManager HRegionServer
　　hadoop7 DataNode   NodeManager HRegionServer

2、安装

　　版本：版本为hbase-0.99.2-bin.tar

　　解压配置环境变量　　

export HBASE_HOME=/home/hadoop/apps/hbase
export PATH=$PATH:$HBASE_HOME/bin

　　配置文件：在conf目录中加入core-site.xml，hdfs-site.xml文件，该文件保持和hadoop的配置文件一致

3、详细配置文件

　　core-site.xml 和当前hadoop集群的配置文件保持一致
