Subject [jira] [Commented] (MAPREDUCE-3614) finalState UNDEFINED if AM is killed by hand
Date Tue, 17 Jan 2012 21:07:41 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3614?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13187999#comment-13187999

Ravi Prakash commented on MAPREDUCE-3614:

Thanks for the pointer Sidd! :) I was running around in circles :(

Currently, if SIGKILL the application it shows up as State:FAILED & FinalStatus:FAILED.
on SIGTERM, its State:FINISHED & FinalStatus:UNDEFINED.

Here's the ideal behavior in my mind:
1. I think a SIGTERM'd AM should lead to a State: FAILED & FinalStatus:FAILED job (if
this was the last AM attempt)
2. The history logs should be copied over to the HS every time (even if this is NOT the last
AM attempt). The Tracking UI should be active.
3. The diagnostic message which shows up in the "Note" coloumn should mention that the AM
was SIGTERMED or something to that effect.

Would you agree?

> If the AM is running and you kill the process (sudo kill #pid), the State in Yarn would
be FINISHED and FinalStatus is UNDEFINED.  The Tracking UI would say "History" and point to
the proxy url (which will redirect to the history server).
> The state should be more descriptive that the job failed and the tracker url shouldn't
point to the history server.
