Yu Li created HBASE-17114:
-----------------------------
Summary: 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)
