Robert Joseph Evans updated YARN-59:
------------------------------------
Fix Version/s: (was: 0.23.4)
0.23.5
> "Text File Busy" errors launching MR tasks
> ------------------------------------------
>
> Key: YARN-59
> URL: https://issues.apache.org/jira/browse/YARN-59
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: Todd Lipcon
> Assignee: Andy Isaacson
> Fix For: 2.0.3-alpha, 0.23.5
>
>
> Some very small percentage of tasks fail with a "Text file busy" error.
> The following was the original diagnosis:
> {quote}
> Our use of PrintWriter in TaskController.writeCommand is unsafe, since that
> class swallows all IO exceptions. We're not currently checking for errors,
> which I'm seeing result in occasional task failures with the message "Text
> file busy" - assumedly because the close() call is failing silently for some
> reason.
> {quote}
> .. but turned out to be another issue as well (see below)
