Subject [jira] [Commented] (HBASE-10000) Initiate lease recovery for outstanding WAL files at the very beginning of recovery
Date Fri, 22 Nov 2013 17:54:38 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10000?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13830154#comment-13830154

Ted Yu commented on HBASE-10000:
--------------------------------

I am currently in China.
Will test on cluster once I come up with next rev of the patch - patch should have used a
threadpool in submitting recoverLease() calls.

Another improvement I want to try, maybe in another JIRA, is to let split log worker to pick
up oldest WAL file(s) first where chance of getting an already closed file is higher. Himanshu
mentioned this idea in HBASE-9873.

> At the beginning of recovery, master can send lease recovery requests concurrently for
outstanding WAL files using a thread pool.
> Each split worker would first check whether the WAL file it processes is closed.
> Thanks to Nicolas Liochon and Jeffery discussion with whom gave rise to this idea.
