> The problem is that disabling security changes zk ACL for resource manager as
> part of AMBARI-19331. After the recent change in HDFS-11403, RM checks znode
> version and fails if it's different than expected.
> The correct fix could be to remove znode during security disabling and do not
> break election znode consistency by manually changing ACL to all. RM should
> create it with proper ACL.
