Xuan Gong updated YARN-1971:
----------------------------
    Component/s: nodemanager

> WindowsLocalWrapperScriptBuilder does not check for errors in generated script
> ------------------------------------------------------------------------------

>                 Key: YARN-1971
>                 URL: https://issues.apache.org/jira/browse/YARN-1971
>             Project: Hadoop YARN
>          Issue Type: Bug
>          Components: nodemanager

> Similar to YARN-1865. The DefaultContainerExecutor.WindowsLocalWrapperScriptBuilder builds
a shell script that contains commands that potentially may fail:
> {code}
> pout.println("@echo " + containerIdStr + " > " + normalizedPidFile +".tmp");
> pout.println("@move /Y " + normalizedPidFile + ".tmp " + normalizedPidFile); 
> {code}
> These can fail due to access permissions, disc out of space, bad hardware, cosmic rays
etc etc. There should be proper error checking to ease troubleshooting.
