>                 Key: HBASE-14408
>                 URL: https://issues.apache.org/jira/browse/HBASE-14408
>             Project: HBase
>          Issue Type: Improvement
>          Components: hbck, IPC/RPC
>    Affects Versions: 1.0.0
>            Reporter: Daisuke Kobayashi
>            Priority: Major
>
> While a regionserver is in busy state, such like plenty of responseTooSlow being thrown, hbck fails because it cannot reach out to the particular regionserver due to SocketTimeoutException. In such scenario, bunch of inconsistencies could be detected, while the regionserver itself doesn't go down, nor does inconsistencies exist actually.
> That should lead a lot of users off track and into a -repair frenzy.
> I'd be nice to have a separate RPC pool for such requests from Hbck.
