Water Chow commented on HBASE-7963:
-----------------------------------
Yes, Enis Soztutar. It's just because that when security enabled, MR do not
have the auth to read the replication paths "/hbase/replication/*" on ZK;
> HBase VerifyReplication not working when security enabled
> ---------------------------------------------------------

> Key: HBASE-7963
> URL: https://issues.apache.org/jira/browse/HBASE-7963
> Project: HBase
> Issue Type: Bug
> Components: Replication, security
> Affects Versions: 0.94.5
> Environment: Security is enabled on both clusters and all principals
> are in the same realm.
> Reporter: Water Chow
> Attachments: HBASE-7963-0.94.patch, HBASE-7963-0.94-v1.patch

> When security is enabled, HBase VerifyReplication fails for two reasons:
> 1.MapReduce do not have the auth to read the replication paths
> "/hbase/replication/*" on ZK;
> 2.VerifyReplication does not get the token for slave cluster, it's different
> from HBASE-7442, this VerifyReplication does not have the output.
