Subject [jira] [Commented] (HBASE-11639) [Visibility controller] Replicate the visibility of Cells as strings
Date Tue, 02 Dec 2014 04:13:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11639?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14230946#comment-14230946
] 

ramkrishna.s.vasudevan commented on HBASE-11639:
------------------------------------------------

bq.Would it be worth backporting to 0.98 the backwards compatibility helper for coprocessor
additions from HBASE-10378 so that we can try to maintain binary compatibility for RegionServerObservers
that don't have the new hook? 
Yes something like that is needed. Which means that in 0.98 the new hook should be called
thro reflections and not directly.  +1 on that.
I need to add some release note for this JIRA. Will do it shortly. Also will raise sub jira
for the ref doc updations.

> 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.
