$VARIABLE and `command` in YARN command lines
John Lilley 2013-11-21, 18:18
We've found that using either
$VARIABLE
Or
`command`
As part of a YARN command-line doesn't really work, because those two things are replaced in the application master context.  Is there a way to escape these elements so that they are passed through to the container launch?
Thanks
John
