Xuan Gong commented on YARN-1303:
---------------------------------
[~tassapola]
Hitesh's suggestion can make the solution much easier. Otherwise, I need to add
more logic to solve this problem, such as how to find a way to figure out which
args belongs to which commands, etc.
I wonder if we can limit distributed shell that can only have one command to
execute by using --shell_command. If we need to execute more than one commands,
we can use the --shell_script. That will simply the solution a lot.
[~vinodkv] Any suggestions ?

> 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.
