Zhihong Yu commented on HBASE-5258:
-----------------------------------
I agree with the last comment @ 23/Jan/12 22:58
My understanding of the feature is that user should validate coprocessor by
choosing the Abort policy for buggy coprocessor in pre-deployment stage. In
production, the chance of buggy coprocessor dropping from individual region(s)
should be low.
The ability of querying imbalanced coprocessors on a region server should be
on-demand feature.

> 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 ?
