NameNode启用HA主备节点进行切换，Hbase启动RegionServers失败

个人参考自己之前的解决办法（切换回NameNode的主备节点的方法）：
https://blog.csdn.net/ZhouyuanLinli/article/details/79396829
后来猜测是不是Kylin中数据引起的，之前未启用HA时添加的，因为Kylin这些测试数据不太重要，所以在Hbase中删除：
hbase(main):006:0> disable_all 'KYLIN_.*'
hbase(main):009:0> drop_all 'KYLIN_.*'
然后在ambari界面重启下zookerper，再重启HBase，结果正常启动，果然是Kylin数据有影响
