一。问题
我们进行完Hbase环境搭建完成后，用命令启动hbase：【bin/start-hbase.sh --> 会在bigdata111启动HMaster，在三台主机都启动HRegionServer】
注意：我们已经在Hbase-site.xml文件中添加了：
<property>
<name>hbase.master.info.port</name>
<value>16010</value>
</property>
1. 然后访问http://bigdata111:16010页面，但是显示错误：
2. 启动hbase shell：【bin/hbase shell】
但是在这个命令启动之后，发生以下错误。而且关于hbase的进程都被杀死。

但是出现页面
二。解决
在logs目录中查看日志：hbase-root-master-bigdata111.log
hbase-root-master-bigdata111.log

此时：才发现只有bigdata111的jps有QuorumPeerMain。 其他两个主机bigdata112和bigdata113没有启动zookeeper。
给三台主机都启动zookeeper，然后发现http://bigdata111:16010访问成功。
