Ted Yu commented on HBASE-17114:
--------------------------------

bq. the multiplier received by the client represents the server state at a 
previous point in time

How about passing the timestamp of when the server raises the exception along 
with the multiplier ?
Client would be able to adjust the waiting period based on these two pieces of 
information.

> 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)
