Yu Li updated HBASE-17114:
--------------------------
    Description: 
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 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)
