Subject [jira] [Commented] (HDFS-9009) Send metrics logs to NullAppender by default
Date Wed, 02 Sep 2015 22:40:46 GMT

    [ https://issues.apache.org/jira/browse/HDFS-9009?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14728164#comment-14728164

Xiaoyu Yao commented on HDFS-9009:
----------------------------------

Patch LGTM. One question: Do we need to change the level from INFO to DEBUG in log4j.properties?
From namenode MetricsLoggerTask, it seems all the metrics logs are written at INFO level.
