Subject [jira] [Commented] (HBASE-8321) Log split worker should heartbeat to avoid timeout
Date Wed, 10 Apr 2013 22:09:16 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8321?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13628338#comment-13628338
] 

Nicolas Liochon commented on HBASE-8321:
----------------------------------------

When it takes time, what are the options available? I mean, if we stop the recovery, the region
will just be unavailable.?
The regionserver is already controlled by a heartbeat, so if the process dies we will know.

> Currently, hlog splitter could spend quite sometime to split a log in case any HDFS issue
and recoverLease/retry opening is needed.  If distributed log split manager times out the
log worker, other log worker to take over will run into the same issue.
> Ideally, we should not need a timeout monitor.  Since we have a timeout monitor for DSL
now, the worker should heartbeat to avoid wrong/unneeded timeouts.
