-------------------------------
As it's already late night on my site, will upload the patch tomorrow.
[~eclark] [~mantonov] and [~ghelmling] especially looking forward to your
thoughts on this idea gentlemen. Thanks.
> Add an option to set special retry pause when encountering
> CallQueueTooBigException

> Key: HBASE-17114
> URL: https://issues.apache.org/jira/browse/HBASE-17114
> Project: HBase
> Issue Type: Bug
> Reporter: Yu Li
> Assignee: Yu Li
>
> As titled, after HBASE-15146 we will throw {{CallQueueTooBigException}}
> instead of dead-wait. This is good for performance for most cases but might
> cause a side-effect that if too many clients connect to the busy, the retry
> requests may come over and over again and RS never got the chance for
> recovering, and the issue will become especially critical when the target
> region is META.
> So here in this JIRA we propose to supply some special retry pause for CQTBE
> in name of {{hbase.client.pause.special}}, and by default it will be 500ms (5
> times of {{hbase.client.pause}} default value)
