Binglin Chang commented on YARN-1450:
-------------------------------------
Let me state the problem more clearly:
Story in YARN-1303:
1. Client accept --shell_command "pwd;ls"
2. Client can not construct a whole cmdline with proper escape support if
shell_command contains special chars like ";", so it write the "pwd;ls" to file
instead
3. AM started, read shell_command from file, get "pwd;ls"
Story in this jira YARN-1450:
1. some app directly launch AM without client, AM directly accept
--shell_command "pwd;ls"
> TestUnmanagedAMLauncher#testDSShell fails on trunk
