Chris Nauroth commented on MAPREDUCE-5655:
------------------------------------------

Regarding the {{mapreduce.application.classpath}} configuration property, this part was already fixed in MAPREDUCE-5442.

>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>          Components: client, job submission
>    Affects Versions: 2.2.0
>         Environment: Client machine is a Windows 7 box, with Eclipse
> Remote: there is a multi node hadoop cluster, installed on Ubuntu boxes (any linux)

> I was trying to run a java class on my client, windows 7 developer environment, which submits a job to the remote Hadoop cluster, initiates a mapreduce there, and then downloads the results back to the local machine.
> General use case is to use hadoop services from a web application installed on a non-cluster computer, or as part of a developer environment.
> The problem was, that the ApplicationMaster's startup shell script (launch_container.sh) was generated with wrong CLASSPATH entry. Together with the java process call on the bottom of the file, these entries were generated in windows style, using % as shell variable marker and ; as the CLASSPATH delimiter.
> I tracked down the root cause, and found that the MrApps.java, and the YarnRunner.java classes create these entries, and is passed forward to the ApplicationMaster, assuming that the OS that runs these classes will match the one running the ApplicationMaster. But it's not the case, these are in 2 different jvm, and also the OS can be different, the strings are generated based on the client/submitter side's OS.
> I made some workaround changes to these 2 files, so i could launch my job, however there may be more problems ahead.
