Hitesh Shah commented on YARN-1303:
-----------------------------------
[~xgong] How about ensuring that the data passed into the client by the user is
correctly passed to the AM and to the launch script in the task. As for
escaping, we can rely on the user to correctly escape chars as needed. For
example, if a user wants to run "echo $FOO" , the user should do "echo \$FOO"
to ensure that the final command run has "echo $FOO"
> 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.
