> while setting the zkacl we used {{getVersion()}} which is dataVersion,Ideally we should
use {{getAversion()}}. If there is any acl changes( i.e relam change/..) ,we set the ACL with
dataversion which will cause BADVersion and *process will not start*. See [here|https://issues.apache.org/jira/browse/HDFS-11403?focusedCommentId=16051804&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16051804]
> {{zkClient.setACL(path, zkAcl, stat.getVersion());}}
