原因：
三台nameNode的状态都为standby状态
Overview 'sonkwo-bj-data001:8020' (standby)
Overview 'sonkwo-bj-data002:8020' (standby)
Overview 'sonkwo-bj-data003:8020' (standby)
解决方法：
1）关闭HDFS集群
stop-dfs.sh
2）启动Zookeeper集群
zk.sh start
3）初始化HA在Zookeeper中状态
hdfs zkfc -formatZK
4）启动HDFS服务
start-dfs.sh
重新执行bin/hive链接成功：

Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions. Consider using a different execution engine (i.e. spark, tez) or using Hive 1.X releases.
