Subject [jira] [Updated] (HBASE-16209) Provide an ExponentialBackOffPolicy sleep between failed region open requests
Date Wed, 30 Nov 2016 00:05:58 GMT

     [ https://issues.apache.org/jira/browse/HBASE-16209?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Ashu Pachauri updated HBASE-16209:
    Attachment: HBASE-16209-addendum.v6.branch-1.patch

This has been open for a while now. I can't repro the findbugs warning locally, and can't
really see why it's complaining! 

HBASE-16209-addendum.v6.branch-1: Rebasing the patch to current branch-1.

> 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
