      Description

      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.
