Subject [jira] [Commented] (HBASE-11639) [Visibility controller] Replicate the visibility of Cells as strings
Date Mon, 01 Dec 2014 18:58:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11639?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14230243#comment-14230243
] 

Sean Busbey commented on HBASE-11639:
-------------------------------------

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? (I'm specifically talking about CoprocessorHost.useLegacyMethod
/ legacyWarning).

Granted, there's no fallback method in this case, so we'd have to clean up the messages a
little.

> 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.
