Hitesh Shah commented on YARN-1303:
-----------------------------------
[~xgong] Have you looked at fixing the underlying issue of passing the args
correctly from the client to the AM? At the moment, they are sent via the AM's
command line which can create problems. To pass to the AM via command-line
requires correct escaping based on type of OS. Or, they could be passed in
through a file which would hide away such aspects.
> Allow multiple commands separating with ";" in distributed-shell

> In shell, we can do "ls; ls" to run 2 commands at once.
> In distributed shell, this is not working. We should improve to allow this to
> occur. There are practical use cases that I know of to run multiple commands
> or to set environment variables before a command.
