Subject [jira] [Commented] (HBASE-8434) Allow users to trade lease recovery for MTTR
Date Thu, 25 Apr 2013 06:24:16 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8434?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13641485#comment-13641485

Enis Soztutar commented on HBASE-8434:
--------------------------------------

-1 on this. Lease recovery should always be default otherwise we will allow data loss. The
only use case, you maybe ok with trading lease recovery with MTTR would be that if all your
table data is skip wal or deferred wal, which is not a common use case at all.

> For environments where lease recovery time can be bounded on the HDFS side through tight
timeouts, provide a toggle for users who want the WAL splitting to continue only after the
lease is recovered and the file is closed.
