[jira] [Created] (MAPREDUCE-6121) JobSubmitter.compareFs doesn't handle HA namespaces

Thomas Graves created MAPREDUCE-6121:
----------------------------------------

             Summary: JobSubmitter.compareFs doesn't handle HA namespaces
                 Key: MAPREDUCE-6121
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6121
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 2.5.0
            Reporter: Thomas Graves


Looking at the JobSubmitter.compareFs it doesn't look like it properly handles HA namespaces.  The code tries to lookup the hostname using InetAddress.getByName, but if you are using namespaces this is going to fail and its going to copy the file when it doesn't need to.
