Subject [jira] [Updated] (YARN-219) NM should aggregate logs when application finishes.
Date Fri, 16 Nov 2012 20:25:12 GMT

     [ https://issues.apache.org/jira/browse/YARN-219?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Robert Joseph Evans updated YARN-219:

    Attachment: YARN-219.txt

This patch is a bit ugly, but it does fix the issue.  I wanted to keep the changes to a minimum
so that it could go into 0.23.5.  If this goes in as is as part of YARN-220 I will clean things
up so that the thread is not started until aggregation is ready to start.

I have manually verified that this works on a 0.23.5 cluster with the patch.

> The NM should only aggregate logs when the application finishes.  This will reduce the
load on the NN, especially with respect to lease renewal.
