NodeManager fails to create containers when NM_LOG_DIR is not explicitly set in the Configuration
-------------------------------------------------------------------------------------------------

                 Key: MAPREDUCE-2644
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-2644
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
            Reporter: Josh Wills
            Assignee: Josh Wills


If the yarn configuration does not explicitly specify a value for the yarn.server.nodemanager.log.dir
property, container allocation will fail on the NodeManager w/an NPE when the LocalDirAllocator
goes to create the temp directory. In most of the code, we handle this by defaulting to /tmp/logs,
but we cannot do this in the LocalDirAllocator context, so we need to set the default value
explicitly in the Configuration.

Marking this as major b/c it's annoying to bump into it when you're getting your first MRv2
cluster up and running. :)
