[jira] [Updated] (YARN-546) mapred.fairscheduler.eventlog.enabled removed from Hadoop 2.0

     [ https://issues.apache.org/jira/browse/YARN-546?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Lohit Vijayarenu updated YARN-546:
----------------------------------

    Attachment: YARN-546.1.patch

It looks like there is nothing much logged in event log and majority seems to be just node updates. If no one votes against to have this removed then here is a patch for review.

> Hadoop 1.0 supported an option to turn on/off FairScheduler event logging using mapred.fairscheduler.eventlog.enabled. In Hadoop 2.0, it looks like this option has been removed (or not ported?) which causes event logging to be enabled by default and there is no way to turn it off.
