问一下老师，有遇到过这种情况吗？yarn 两个RM 都处于Standby状态，尝试了ambari里面各种重启都没有效果。
yarn resourcemanager -format-state-store的话，节点报了这个错

FATAL resourcemanager.ResourceManager: Error starting ResourceManager
org.apache.zookeeper.KeeperException$NoAuthException: KeeperErrorCode = NoAuth for /rmstore/ZKRMStateRoot/RMDTSecretManagerRoot

看了下日志
日志里面是这个异常
2020-03-27 07:17:15,875 ERROR client.AsyncProcess - Failed to get region location
java.io.IOException: org.apache.zookeeper.KeeperException$NoNodeException: KeeperErrorCode = NoNode for /atsv2-hbase-unsecure/meta-region-server

apache 论坛也有讨论，像是什么版本问题
https://issues.apache.org/jira/browse/YARN-1861

暂时还没找到解决思路
