原因是hiveServer2無法在zookeeper中創建節點，可能zookeeper出了問題，可以檢查一下是否創建了zk節點。進入zk查看是否有創建 hiveserver2

/usr/hdp/current/zookeeper-client/bin/zkCli.sh
ls  /     //查看全部的節點

ls /hiveserver2    //查看hiveserver2節點內容

這邊看到hiveserver2 是已經創建了，導致hiveserver2 不能夠再加入zookeeper中。
刪除已有的hiveserver2 ，重啓hiveserver2 ，可以看到新的hiveserver2 已經加入到zk中了。

hiveserver2 正常了。
