Xuan Gong commented on YARN-1303:
---------------------------------

Did the test on a single cluster:
Input:
{code}
hadoop jar hadoop-yarn-project-3.0.0-SNAPSHOT/share/hadoop/yarn/hadoop-yarn-applications-distributedshell-3.0.0-SNAPSHOT.jar org.apache.hadoop.yarn.applications.distributedshell.Client --jar hadoop-yarn-project-3.0.0-SNAPSHOT/share/hadoop/yarn/hadoop-yarn-applications-distributedshell-3.0.0-SNAPSHOT.jar --shell_command pwd --help
{code}

chosen Output:
{code}
 -shell_command <arg>        Shell command to be executed by the
                             Application Master. Does not support multiple
                             --shell_command options, multiple shell
                             commands and command pipline. For multiple
                             shell commands or command pipeline, please
                             create a shell script and use --shell_script
                             option
 -shell_script <arg>         Location of the shell script to be executed.
                             Support only one --shell_script option. For
                             multiple shell scripts, combine them into one
                             shell script
{code}

> 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.
