Subject [jira] Commented: (HADOOP-4413) Capacity Scheduler to provide a scheduler history log to record actions taken and why
Date Thu, 16 Oct 2008 01:50:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4413?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12640032#action_12640032
] 

Mac Yang commented on HADOOP-4413:
----------------------------------

For the scheduler log entries that are meant for human consumption, there are definitely pros
and cons as to whether to put them in the JobTracker log. However, in a fashion similar to
the job log history, it would be very nice if the scheduler can output structured events and
metrics into a separate file so that it's easier to parse.

made and actions taken by the scheduler.
