[jira] [Commented] (YARN-194) Log handling in case of NM restart.

    [ https://issues.apache.org/jira/browse/YARN-194?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13704053#comment-13704053 ] 

Omkar Vinit Joshi commented on YARN-194:
----------------------------------------

we may or may not want to delete the logs when NM restarts.
* if Application is still running then we may not want to delete the logs and wait till the application finishes or we may just aggregate logs during restart.
* if application is finished then there should be someway to specify whether or not to aggregate / remove logs.

any thoughts?

> Currently, if an NM restarts - existing logs will be left around till they're manually cleaned up. The NM could be improved to handle these files.
