说明
zookeeper和hadoop在头两篇文章已经介绍了，本文基于之前安装的集群安装hbase，安装的节点如下（标红的为本次安装）：
机器 |
安装软件 |
进程 |
focuson1 |
zookeeper;hadoop namenode;hadoop DataNode;hbase master;hbase regionrerver |
JournalNode; DataNode; QuorumPeerMain; NameNode; NodeManager;DFSZKFailoverController；HMaster；HRegionServer |
focuson2 |
zookeeper;hadoop namenode;hadoop DataNode;yarn;hbase master;hbase regionrerver |
NodeManager;ResourceManager;JournalNode; DataNode; QuorumPeerMain; NameNode; DFSZKFailoverController；HMaster；HRegionServer |
focuson3 |
zookeeper;hadoop DataNode;yarn;hbase regionrerver |
NodeManager;ResourceManager;JournalNode; DataNode; QuorumPeerMain；HRegionServer |
注：zookeeper和hadoop戳链接：
zookeeper搭建
hadoop搭建
安装步骤
1、将包上传至用户家目录，解压
cd/usr/local/src/
mkdir hbase
mv ~/hbase-1.4.3. .
tar -xvf hbase-1.4.3.
rm -f hbase-1.4.3.2、配置类
配置文件一：$HBASE_HOME/conf/
export HBASE_MANAGES_ZK=false//默认hbase管理zookeeper，需要制定zookeeper的配置文件路径，修改成false，链接我们自己搭建的zookeeper集群
export JAVA_HOME=/usr/local/src/java/jdk1.7.0_51配置文件二：$HBASE_HOME/conf/
<configuration>
<property>
<name></name>
<!--链接两个ns1,ns1在hadoop集群中指向两个namenode，实现高可用，如果写定一个namenode，当该namenode为standby时，会报错
该配置不需写端口-->
<value>hdfs://ns1/hbase</value>
</property>
<!--指定为分布式-->
<property>
<name></name>
<value>true</value>
</property>
<!--指定两个master，注册zookeeper监听，实现高可用-->
<property>
<name></name>
<value>focuson1:60000,focuson2:60000</value>
</property>
<!--zookeeper集群-->
<property>
<name></name>
<value>focuson1:2181,focuson2:2181,focuson3:2181</value>
</property>
<!--该配置必须有，要不访问不了web界面-->
<property>
<name></name>
<value>60010</value>
</property>
</configuration>
配置三：把hadoop的文件考到hbase的配置路径下
cp /usr/local/src/hadoop/hadoop-2.6.0/etc/hadoop/ /usr/local/src/hbase/hbase-1.4.3/conf/3、启动
在focuson1上执行（启动focuson1的master，以及三台regionserver）：
[root@focuson1 hbase-1.4.3]# ./bin/
running master, logging to /usr/local/src/hbase/hbase-1.4.3/logs/hbase-root-master-focuson1.out
focuson3: running regionserver, logging to /usr/local/src/hbase/hbase-1.4.3/bin/../logs/hbase-root-regionserver-focuson3.out
focuson1: running regionserver, logging to /usr/local/src/hbase/hbase-1.4.3/bin/../logs/hbase-root-regionserver-focuson1.out
focuson2: running regionserver, logging to /usr/local/src/hbase/hbase-1.4.3/bin/../logs/hbase-root-regionserver-focuson2.out[root@focuson2 hbase-1.4.3]# ./bin/
running master, logging to /usr/local/src/hbase/hbase-1.4.3/bin/../logs/hbase-root-master-focuson2.out
focuson3: regionserver running as process 6705. Stop it first.
focuson1: regionserver running as process 17806. Stop it first.
focuson2: regionserver running as process 13949. Stop it first.
4 验证。
验证一：发现focuson1为active,focuson2为standby。
kill掉focuson1的hmaster进程，发现focuson2为active（不贴图了）
验证二：无论namenode为哪一个启动，hbase都能正常运行。
5、连接hdfs时出现的几个小问题。
问题一.不链接两个namenode实现高可用时，当链接focuson1，而此时focuson1正好为standby状态时，会报下面的错：
2018-05-02 00:01:20,746 FATAL [focuson1:16000.activeMasterManager] : Failed to become active master

at (:838)
at (:821)
at $ClientNamenodeProtocol$2.callBlockingMethod()
at $Server$ProtoBufRpcInvoker.call(:619)
at $Server.call(:962)问题二、当配置高可用之后，Hmaster正常，HregionServer出现如下错误：
2018-05-02 01:36:41,083 ERROR [main] : Region server exiting
