Anoop Sam John commented on HBASE-11639:
----------------------------------------
bq.Just update the AC at the same time the new hooks go in?
Yes. AC, as it is our internal CP impl, is not having any issue. We discussed
here abt this later.
The one concern I have is as follows
User having a RegionServerObserver CP impl (Implementing RegionServerObserver)
and this is based on older 98 version. Later he has upgraded to newer version
of 98 which is having these extra method in CP. If no recompile there is no
need to add the dummy impl. But the core code will try to call this hook on
the existing CP impl object and will throw RTE. If abort on error in CP is
true this will cause to RS to abort. Do we need to guard this case? In the past
we have added new CP hooks in point releases. So what can be general agreement
in this area?

> Key: HBASE-11639
> URL: https://issues.apache.org/jira/browse/HBASE-11639
> Project: HBase
> Issue Type: Improvement
> Components: Replication, security
> Affects Versions: 0.98.4
> Reporter: ramkrishna.s.vasudevan
> Assignee: ramkrishna.s.vasudevan
> Labels: VisibilityLabels
> Fix For: 2.0.0, 0.98.7, 0.99.1
>
>
> This issue is aimed at persisting the visibility labels as strings in the WAL
> rather than Label ordinals. This would help in replicating the label
> ordinals to the replication cluster as strings directly and also that after
> HBASE-11553 would help because the replication cluster could have an
> implementation as string based visibility labels.
