Ted Yu commented on HBASE-5258:
-------------------------------
0.94 patch doesn't break backwards compatibility.
Handling of coprocessors is kept. It is just always reporting 0 coprocessors in
RegionLoad.
> Move coprocessors set out of RegionLoad

> When I worked on HBASE-5256, I revisited the code related to Ser/De of
> coprocessors set in RegionLoad.
> I think the rationale for embedding coprocessors set is for maximum
> flexibility where each region can load different coprocessors.
> This flexibility is causing extra cost in the region server to Master
> communication and increasing the footprint of Master heap.
> Would HServerLoad be a better place for this set ?
> If required, region server should calculate disparity of loaded coprocessors
> among regions and send report through HServerLoad
