Xuan Gong commented on YARN-1314:
---------------------------------
bq.Can each argument be complex as I describe above? It is matching regular
shell behavior.
I think so.
Try this command :
{code}
--shell_command echo --shell_args YARN HADOOP "'\\\"\\\$MYARG\\\"'" -shell_env
"MYARG=myval"
{code}
We can get the expect output. As long as we give the valid argument, it will
give the expected output.
> Cannot pass more than 1 argument to shell command

> 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
