Subject [jira] [Commented] (HBASE-6505) Investigate shared RegionObserver state
Date Sat, 04 Aug 2012 05:26:02 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6505?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13428562#comment-13428562

Andrew Purtell commented on HBASE-6505:

bq. So I should probably key that map with a String (which would Class.getName()).

Makes sense.

bq. When an Environment is blacklisted, it is only that environment, is it then safe to remove
the classes part from the sharedDataMap (since there might be other instance of the same class,
but loaded from a different class loader).

Thinking on this, perhaps we can defer that until CPs can actually be unloaded. Blacklisting
is only a half measure. If I've seen in an RS log that a CP has been blacklisted my thinking
is it's time to cycle the RS. Who knows what damage has been done. And attempts to limit heap
usage of the map don't make much sense IMO for the same reason, the CP could leak objects
