Subject [jira] [Commented] (HBASE-13602) Add an option to fail wal recovery when lease recovery fails
Date Thu, 14 May 2015 13:38:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13602?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14543673#comment-14543673

Sean Busbey commented on HBASE-13602:

Sure, that sounds reasonable as a first pass. I figured there had to be some "failed" state
already, since there are already other problems that might come up. In this case, I suspect
that operator intervention is necessary so if we don't already have a "help please" failure
state, we should probably add one.

> 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)
