解决办法：Maven中引入hbase-server-1.2.0-cdh5.12.2.jar
异常二：Failed to connect to /192.186.0.36 for block, add to deadNodes and continue. java.net.NoRouteToHostException:
服务器是双网段192和10开头，而办公网段是：10.96开头的IP，本地设置的host文件也是连接的10,96的hostName映射，脚本运行时自动连接192.168的网段，导致一直无法连接到集群。
解决办法：
<property> <name>dfs.client.use.datanode.hostname</name> <value>true</value> </property>
