> 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
