[jira] [Commented] (HBASE-13602) Add an option to fail wal recovery when lease recovery fails

    [ https://issues.apache.org/jira/browse/HBASE-13602?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14522048#comment-14522048 ] 

Nick Dimiduk commented on HBASE-13602:
--------------------------------------

Detecting and preserving data in a scenario of unintended data loss sounds like something we should do by default, even on branch-1.

> 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)
