Subject [jira] [Updated] (HBASE-5258) Move coprocessors set out of RegionLoad, region server should calculate disparity of loaded coprocessors among regions and send report through HServerLoad

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

    Priority: Critical  (was: Major)

Raising priority as this task is about making the correct design choices.

> 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 ?
