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.
> Improve cancellation management in the rpc layer

> Key: HBASE-11564
> URL: https://issues.apache.org/jira/browse/HBASE-11564
> Project: HBase
> Issue Type: Bug
> Components: Client
> Affects Versions: 1.0.0, 2.0.0
> Reporter: Nicolas Liochon
> Assignee: Nicolas Liochon
> Fix For: 0.99.0, 2.0.0
>
> Attachments: 11564.v1.patch, 11564.v2.patch
>
>
> 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.
