Subject [jira] [Commented] (HBASE-16209) Provide an ExponentialBackOffPolicy sleep between failed region open requests
Date Thu, 14 Jul 2016 00:12:20 GMT

Joseph commented on HBASE-16209:
--------------------------------

There appears to be a pre-existing bug with the Web UI and RegionTransitions. I will try to
fix that bug in this fix, but it would be nice if I could get some feedback on the AssignmentManager
code. Thanks!

> Related to HBASE-16138. As of now we currently have no pause between retrying failed
region open requests. And with a low maximumAttempt default, we can quickly use up all our
regionOpen retries if the server is in a bad state. I added in a ExponentialBackOffPolicy
so that we spread out the timing of our open region retries in AssignmentManager. Review board
