> The DistributedShell has an option shell_script to let user specify a shell script which will be executed in containers. But the issue is that the shell_command option is a must, so if both options are set, then every container executor will end with exitCode=1. This is because DistributedShell executes the shell_command and shell_script together. For example, if shell_command is 'date' then the final command to be executed in container is "date `ExecShellScript.sh`", so the date command will treat the result of ExecShellScript.sh as its parameter, then there will be an error. 
> To solve this, the DistributedShell should not use the value of shell_command option when the shell_script option is set, and the shell_command option also should not be mandatory.
