Subject [jira] [Commented] (FLINK-2224) JobManager log does not contain root cause and stack trace of exceptions
Date Mon, 15 Jun 2015 15:00:02 GMT

    [ https://issues.apache.org/jira/browse/FLINK-2224?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14586147#comment-14586147

Ufuk Celebi commented on FLINK-2224:
------------------------------------

Yes, I agree. Access to JM logs is currently easier via the web interface as well.

I've looked in to the JM and the respective Akka message is JobStatusChanged (l 287). The
error cause contains the root cause as well, but only the exception message is printed. It's
an easy fix and I vote to include it into the release. If you haven't looked into this yet,
I can do the fix.

> While running cluster tests with failing jobs I noticed that the JobManager log file
does neither contain the root cause of the failure nor a stack trace of it. The error was
not sufficient resources available for scheduling. 
> For the purpose of debugging, it is crucial to have this information in the log file.
