Mikhail Antonov commented on HBASE-13351:
-----------------------------------------
I don't really think type of blocking queue matters in this case. It's just
without this patch the requests get distributed between call* and priority*
executors, and now most of them (in this particular test) go thru the latter
one. Just saturation I think. Which OS are you using? On my mac 10 handlers
from IDE don't pass always. I'll set it to something higher just to be on the
safe side. I don't think it's going to be critical (as all threads get shut
down when test completes).

> HBASE-12071, among other things, introduced annotating RPC methods to give
> certain methods priority over others. Namely, this helps ensure that client
> requests cannot starve out internal RPC between master and regionserver.
> Similarly, we can do the same thing for Master RPC methods that are invoked
> by RS's.
