Subject [jira] [Commented] (HDFS-11403) Zookeper ACLs on NN HA enabled clusters to be handled consistently
Date Fri, 16 Jun 2017 11:55:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11403?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16051804#comment-16051804

Brahma Reddy Battula commented on HDFS-11403:

Sorry for landing late here,any purpose why we always use {{stat.getVersion()}} why not {{stat.getAversion()}}..?
1083	          zkClient.setACL(path, zkAcl, stat.getVersion());
 *There can be chance that aclversion(like below case) will be higher than {{dataversion}}
which might cause {{Bad Version}} and fail .* 
cversion = 0
dataVersion = 1
aclVersion = 5
ephemeralOwner = 0x0
dataLength = 4

Please correct me If I am wrong.

> On clusters where NN HA is enabled zookeper ACLs need to be handled consistently when
enabling security.
> The current behavior is as follows:
> * if HA is enabled before the cluster is made secure, proper ACLs are only set on the
leaf znodes, while there's no ACLs set on the path (eg.:/hadoop-ha/mycluster/ActiveStandbyElectorLock)
> * if HA is enabled after the cluster is made secure ACLs are set on the root znode as
