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.
