Subject [jira] [Commented] (HBASE-13602) Add an option to fail wal recovery when lease recovery fails
Date Thu, 30 Apr 2015 20:25:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13602?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14522190#comment-14522190

Sean Busbey commented on HBASE-13602:
-------------------------------------

I agree in principle but this has been the behavior since at least HBASE-8449, which means
all of 0.98.

It's a big change in behavior to go from folks having slow-to-recover problems to hard-fail
problems.

> Currently, if lease recovery doesn't succeed over an extended timeout (default 15 minutes),
then we issue a log message about possible data loss and continue with recovering the edits
in that file.
> In some deployments this potential for dataloss might be unacceptable. In those situations
it would be good to have a configurable setting that marks the recovery failed instead. Should
default to off (at least in branch-1)
