Tassapol Athiapinya commented on YARN-1303:
-------------------------------------------
Script option can be substituted in all cases. I think this is for convenient
use and for the purpose to have as similar behavior as normal shell as possible.
> Allow multiple commands separating with ;

> Project: Hadoop YARN
> Issue Type: Improvement

>
> 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.
