Enis Soztutar commented on HBASE-11564:
---------------------------------------

If I remember correctly, I was able to repro this while running IntegrationTestTimeBoundedRequestsWithRegionReplicas
with CM. We can come back to this if we see it again in testing.

> The current client code depends on interrupting the thread for canceling a request. It's
actually possible to rely on a callback in protobuf.
> The patch includes as well various performance improvements in replica management. 
> On a version before HBASE-11492 the perf was ~35% better. I will redo the test with the
last version.
