Todd Lipcon commented on HBASE-3401:
------------------------------------
Stack: yea, the syntax for defining an annotation is wacky. I had to look it up
mysefl.
bq. Will this all work if someone subclasses and overrides HRS methods?
Yes, it should - getAnnotation() will return inherited annotations as well.
Though perhaps it should be made a protected @interface instead of private for
subclassers?
Though, I thought we were discouraging subclassing these days in favor of CPs?

> I manufactured an imbalanced cluster so one region server had 300 regions and
> the others had very few. I then ran balancer while hitting the high-load
> region server with YCSB. I observed that the rate of load shedding was VERY
> slow since the closeRegion IPCs were getting stuck at the back of the IPC
> queue.
> All of these important master->RS RPC calls should be set to high priority.
