Subject [jira] [Commented] (HBASE-6505) Investigate shared RegionObserver state
Date Sat, 04 Aug 2012 03:42:02 GMT

    [ https://issues.apache.org/jira/browse/HBASE-6505?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13428550#comment-13428550

Lars Hofhansl commented on HBASE-6505:

Actually while trying to write a test for this to ensure that the maps for multiple instances
of the same CP class are identical, I found that they are in fact not.

A new RegionCoprocessorHost is created for each region (see HRegion.<init>), not per
RegionServer as I had assumed, defeating the purpose of what I had in mind.

Back to the drawing board. The sharedDataMap could be made part of RegionServerServices, instead
(and thus reside with the RegionServer).
