Subject [jira] Commented: (HADOOP-4413) Capacity Scheduler to provide a scheduler history log to record actions taken and why
Date Wed, 15 Oct 2008 11:25:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-4413?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12639816#action_12639816
] 

Vinod K V commented on HADOOP-4413:
-----------------------------------

All the scheduler log goes to the same log as JobTracker now. May be we should move the scheduler
logging to a new log file. I already see that scheduler logging statements and JT logging
statements get drowned in each other. And in debug level, the situation only gets worse. But
one big advantage we can have by a single log file is the time-line of various events occurring
in a scheduler w.r.t events happening in the JT.

> It would be very useful if the capacity scheduler can provide a log that record the decisions
made and actions taken by the scheduler.
