>          Components: nodemanager
>    Affects Versions: 2.6.0
>         Environment: Windows
>            Reporter: Craig Welch
>            Assignee: Craig Welch
>             Fix For: 2.6.0

> PROBLEM: User is getting "No Logs available for Container Container_<number>" when
setting the yarn.nodemanager.log-dirs to any drive letter other than C:
> STEPS TO REPRODUCE:
> On Windows
> 1) Run NodeManager on C:
> 2) Create two local drive partitions D: and E:
> 3) Put yarn.nodemanager.log-dirs = D:\nmlogs or E:\nmlogs
> 4) Run a MR job that will last at least 5 minutes
> 5) While the job is in flight, log into the Yarn web ui , <resource_manager_server:8088>/cluster
> 6) Click on the application_id<number>
> 7) Click on the logs link, you will get "No Logs available for Container Container_<number>"
> ACTUAL BEHAVIOR: Getting an error message when viewing the container logs
> EXPECTED BEHAVIOR: Able to use different drive letters in yarn.nodemanager.log-dirs and
not get error
> NOTE: If we use the drive letter C: in yarn.nodemanager.log-dirs, we are able to see
the container logs while the MR job is in flight.
