[jira] Commented: (HADOOP-5846) Log job history events to a common dump file

    [ https://issues.apache.org/jira/browse/HADOOP-5846?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12709761#action_12709761 ] 

Arun C Murthy commented on HADOOP-5846:
---------------------------------------

Is the proposal to add another 'log' statement in JobHistory with the lock on the JobTracker? If so, that is a slippery slope...

> As of today all the jobhistory events are logged to separate files. It would be nice to also dump all this info into a common file so that external tools (e.g Chukwa) can harvest history info. Job configuration should also be dumped. Whether to use a same log file for history dumps and configuration dumps should be configurable (by default everything goes to one file).
