Subject [jira] [Commented] (HBASE-13677) RecoverableZookeeper WARNs on expected events
Date Mon, 18 May 2015 02:21:05 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13677?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14547458#comment-14547458

Sean Busbey commented on HBASE-13677:

Overall, the patch looks good. We don't have any regular means of testing log messages, sadly.

It looks like there are some additional messages in the delete method that are basically "already
deleted, presume we did it earlier" at INFO. Could you tune these down to DEBUG as well?

some nits:

* A patch this simple usually doesn't need a review board.
* In the future, please generate your patch files using format-patch so that your authorship
and commit message will already be in place. e.g. {{git format-patch --stdout origin/master
> HBASE-13677.1.patch}}
