[jira] [Commented] (YARN-1100) Giving multiple commands to ContainerLaunchContext doesn't work as expected

["Omkar Vinit Joshi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/YARN-1100?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13751962#comment-13751962 ] 

Omkar Vinit Joshi commented on YARN-1100:
-----------------------------------------

I think inserting semicolon is the better idea rather than expecting users to do the same.

> 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.
