Subject [jira] [Commented] (YARN-4142) add a way for an attempt to report an attempt failure
Date Thu, 10 Sep 2015 18:56:46 GMT

    [ https://issues.apache.org/jira/browse/YARN-4142?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14739361#comment-14739361

Sunil G commented on YARN-4142:

Hi [~steve_l]
I have a doubt here. In NodeManager {{ContainerImpl}}, we set  diagnostics and exitcode for
few error cases. So here  "application explicitly terminates an attempt" means AM kills by
itself for some reasons, or AM container/attempt is killed by cli command.

> Currently AMs can report a failure with exit code and diagnostics text —but only when
exiting to a failed state. If the AM terminates for any other reason there's no information
held in the RM, just the logs somewhere —and we know they don't always last.
> When an application explicitly terminates an attempt, it would be nice if it could  optionally
report something to the RM before it exited. The most recent set of these could then be included
in Application Reports, so allowing client apps to count attempt failures and get exit details.
