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).
