>             Project: HBase
>          Issue Type: Bug
>            Reporter: Yu Li
>            Assignee: Yu Li
>         Attachments: HBASE-17114.branch-1.patch, HBASE-17114.patch, 
> HBASE-17114.v2.patch, HBASE-17114.v3.patch, HBASE-17114.v3.patch,

> 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 RS, that 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 add a new property in name of 
> {{hbase.client.pause.cqtbe}} to make it possible to set a special-longer 
> pause for CallQueueTooBigException, and by default it will use the setting of 
> {{hbase.client.pause}}
