Description

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

zkClient.setACL(path, zkAcl, stat.getVersion());
