HBase的分布模式（3、5节点）安装
1、分别对djt11、djt12、djt13、djt14、djt15的启动进程恢复到没有任何启动进程的状态。
[hadoop@djt11 hadoop]$ pwd
[hadoop@djt11 hadoop]$ jps
[hadoop@djt12 hadoop]$ jps
[hadoop@djt13 hadoop]$ jps
[hadoop@djt14 hadoop]$ jps
[hadoop@djt15 hadoop]$ jps
2、切换到app安装目录
下载HBase压缩包
[hadoop@djt11 hadoop]$ pwd
[hadoop@djt11 hadoop]$ cd ..
[hadoop@djt11 app]$ pwd
[hadoop@djt11 app]$ ls
[hadoop@djt11 app]$ rz

[hadoop@djt11]$ tar -zxvf hbase-0.98.19-hadoop2-bin.tar.gz
[hadoop@djt11 app]$ pwd
[hadoop@djt11 app]$ ls
[hadoop@djt11 app]$ mv hbase-0.98.19-hadoop2 hbase
[hadoop@djt11 app]$ rm -rf hbase-0.98.19-hadoop2-bin.tar.gz
[hadoop@djt11 app]$ ls

vi hbase-env.sh
#export JAVA_HOME=/usr/java/jdk1.6.0/
修改为，
export JAVA_HOME=/home/hadoop/app/jdk1.7.0_79
export HBASE_MANAGES_ZK=true
这里，有一个知识点。
进程HQuorumPeer，设HBASE_MANAGES_ZK=true，在启动HBase时，HBase把Zookeeper作为自身的一部分运行。
进程QuorumPeerMain，设HBASE_MANAGES_ZK=false，先手动启动Zookeeper，再启动HBase。

这个脚本，我们之前在搭建hadoop的5节点时，已经写好并可用的。这里，我们查看下并温习。不作修改
将djt11的hbase分发到slave，即djt12、djt13、djt14、djt15
[hadoop@djt11 tools]$ pwd
[hadoop@djt11 tools]$ cd /home/hadoop/app/
[hadoop@djt11 app]$ ls
[hadoop@djt11 app]$ deploy.sh hbase /home/hadoop/app/ slave
查看分发后的结果情况
表明，分发成功！
接下来，分别也跟djt11亿元，进行djt12、djt13、djt14、djt15的配置。
djt12的配置:
[hadoop@djt12 hbase]$ pwd

[hadoop@djt12 hbase]$ cd conf/

都是已经配置好了的
[hadoop@djt12 conf]$ vi backup-masters
都是之前已经配置好了的

（注意，我的图片里是错误的！） 因为是做了高可用，是cluster1而不是单独的djt11。cluster1包括了djt11和djt12

.HBase的分布模式（3、5节点）的启动
这里，只需启动sbin/start-dfs.sh即可。
不需sbin/start-all.sh （它包括sbin/start-dfs.sh和sbin/start-yarn.sh）
启动zookeeper，是因为，hbase是建立在zookeeper之上的。数据是保存在hdfs。
[hadoop@djt11 app]$ jps
[hadoop@djt11 app]$ ls
[hadoop@djt11 app]$ cd hadoop/
[hadoop@djt11 hadoop]$ ls
[hadoop@djt11 hadoop]$ sbin/start-dfs.sh

[hadoop@djt15 app]$ ls
[hadoop@djt15 app]$ cd hbase/
[hadoop@djt15 hbase]$ pwd
[hadoop@djt15 hbase]$ jps
那么，djt11的master被杀死掉，则访问不到了。
然后，我们再把djt11的master启起来，
则，djt11由不可访问，变成备用的master了。djt12依然还是主用的master
成功！
