> Giving multiple commands to ContainerLaunchContext doesn't work as expected
> ---------------------------------------------------------------------------
>
> Key: YARN-1100
> URL: https://issues.apache.org/jira/browse/YARN-1100
> Project: Hadoop YARN
> Issue Type: Bug
> Components: api, nodemanager
> Affects Versions: 2.1.0-beta, 2.7.2
> Reporter: Sandy Ryza
> Attachments: YARN-1100.patch
>
>
> A ContainerLaunchContext accepts a list of commands (as strings) to be
> executed to launch the container. I would expect that giving a list with the
> two commands "echo yolo" and "date" would print something like
> {code}
> yolo
> Mon Aug 26 14:40:23 PDT 2013
> {code}
> Instead it prints
> {code}
> yolo date
> {code}
> This is because the commands get executed with:
> {code}
> exec /bin/bash -c "echo yolo date"
> {code}
> To get the expected behavior I have to include semicolons at the end of each
> command. At the very least, this should be documented, but I think better
> would be for the NM to insert the semicolons.
