Subject [jira] [Commented] (HADOOP-11134) Change the default log level of bin/hadoop from INFO to WARN
Date Wed, 12 Aug 2015 15:33:46 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11134?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14693687#comment-14693687

Junping Du commented on HADOOP-11134:
-------------------------------------

I would be very conservative to change default log level behavior (no matter trunk or branch-2).

There should be many places we assume LOG.info will log some important messages (don't have
to be warn, as it could be information in normal behavior, like real port number for servers
started with ephemeral port settings) with default settings. The unimportant messages in normal
case should be set as debug level which should be enough. I don't think it is necessary to
review all LOG.info cases (huge or even impossible effort) to make such a trivial changes
without any significant benefit.
I prefer to close this issue as "not a problem". Thoughts?

> Split from HADOOP-7984. Currently bin/hadoop script outputs INFO messages. How about
making it to output only WARN and ERROR messages?
