Chris Nauroth updated YARN-493:
-------------------------------

    Description: Both product and test code contain some platform-specific assumptions, such as availability of bash for executing a command in a container and signals to check existence of a process and terminate it.  (was: The tests contain some platform-specific assumptions, such as availability of bash for executing a command in a container and signals to check existence of a process and terminate it.)
        Summary: NodeManager job control logic flaws on Windows  (was: TestContainerManager fails on Windows)

I'm expanding the scope of this jira to cover some flaws I've discovered in NodeManager's job control logic on Windows:

# Windows was erroneously flagged as supporting setsid, which caused prepending of a '-' character to the job ID passed to winutils.
# Exit code from job terminated by winutils task kill differed from expectations in YARN Java code, so that it couldn't tell the difference between a killed container vs. a container that had exited with failure.
# Multiple tests were relying on bash scripts and signals for launching and controlling containers.

I have a patch in progress.  With the expanded scope, the patch will fix the following tests on Windows: {{TestContainerLaunch}}, {{TestContainerManager}}, and {{TestNodeManagerShutdown}}.
