Zhihong Yu updated HBASE-5258:
------------------------------
Description:
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

Summary: Move coprocessors set out of RegionLoad (was: Move
coprocessors set out of RegionLoad, region server should calculate disparity of
loaded coprocessors among regions and send report through HServerLoad)
