Eric Yang resolved YARN-7381.
-----------------------------
Resolution: Fixed
When NM_LOG_CONTAINER_DEBUG_INFO is enabled, and there is a problem to execute
container script. A ExitCodeException would be thrown to notify the execution
failure. By default, I think this is correct to make sure failure are notified
to caller. The past behavior swallows the exception, which is not exactly
correct. Most people don't use DefaultContainerExecutor, and container
launcher code is usually successful. This is the reason that swallowed
exception was not noticeable.
TestContainerLaunch unit test is not quite accurate because the script
instructed to execute "hello" script, which does not exist. Hence, the
throwing of exception is the proper behavior. I am inclined to close this
issue as fixed. When ExitCodeException triggers more exception else where, it
will help developer to look at the root causes that trigger launcher failures
more closely.
