>             Project: Hadoop YARN
>          Issue Type: Bug
>            Reporter: Akshat Bordia
>            Assignee: Akshat Bordia
>            Priority: Major

> Steps to Reproduce:
> 1. Add auxillary service configuration such as spark_shuffle.
> 2. Add following configuration to provide custom classpath for the auxillary 
> service:
> yarn.nodemanager.aux-services.spark_shuffle.classpath=D:\Spark\yarn\*
> 3. Start NM
> Expected Behavior:
> 1. NM should start along with the auxillary service.
> Actual Behavior:
> 1. NM keeps crashing due to auxillary service not being able to start as it 
> is not able to find required classes.
> java.lang.ClassNotFoundException: 
> org.apache.spark.network.yarn.YarnShuffleService
> Potential Fix:
> Using File.separator instead of "\" to make glob expansion OS agnostic.
