Tassapol Athiapinya commented on YARN-1314:
-------------------------------------------

[~xgong] can you please give an example of command to run multiple arguments? Ideally each argument should allow spaces in between also.

As an example, similar to shell command, we can do:
cp "my file  1.txt" "my file  2.txt"
This can be complex by allowing \" inside each argument in addition to having spaces.
cp "my\"file  1.txt" "my\"file  2.txt"

> Distributed shell cannot accept more than 1 parameters in argument parts.
> All of these commands are treated as 1 parameter:
> /usr/bin/yarn  org.apache.hadoop.yarn.applications.distributedshell.Client -jar <distrubuted shell jar> -shell_command echo -shell_args "'"My   name"                "is  Teddy"'"
> /usr/bin/yarn  org.apache.hadoop.yarn.applications.distributedshell.Client -jar <distrubuted shell jar> -shell_command echo -shell_args "''My   name'                'is  Teddy''"
> /usr/bin/yarn  org.apache.hadoop.yarn.applications.distributedshell.Client -jar <distrubuted shell jar> -shell_command echo -shell_args "'My   name'                'is  Teddy'"
