Subject [jira] [Commented] (HBASE-13602) Add an option to fail wal recovery when lease recovery fails
Date Thu, 30 Apr 2015 21:03:06 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13602?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14522265#comment-14522265

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

But that doesn't mark it failed, it just keeps it retrying. I'd like to call things to the
attention of an operator, since something probably needs to be done to e.g. ensure the RS
is dead and then force recovery.

> 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)
