---------------------------------

             Summary: Windows: Node manager cannot serve up log files via the web user interface when yarn.nodemanager.log-dirs to any drive letter other than C: (or, the drive that nodemanager is running on)
                 Key: YARN-2741
                 URL: https://issues.apache.org/jira/browse/YARN-2741
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Craig Welch


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.
