Yu Li updated HBASE-17114:
--------------------------
Release Note: In HBASE-17114 we introduced a new property
hbase.client.pause.cqtbe which makes it possible to set a longer pause for
CallQueueTooBigException (CQTBE), it's disabled by default and
{{hbase.client.pause}} will still be used for CQTBE. Set this property to a
higher value if you observe frequent CQTBE from the same RegionServer and
the call queue there keeps full
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 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}}

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)
