Subject [jira] Created: (MAPREDUCE-747) In Job Tracker logs, some host locations [either in SPLITS or in HOSTNAME subrecords] have numeric host locations

In Job Tracker logs, some host locations [either in SPLITS or in HOSTNAME subrecords] have
numeric host locations
-----------------------------------------------------------------------------------------------------------------

                 Key: MAPREDUCE-747
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-747
             Project: Hadoop Map/Reduce
          Issue Type: Bug
            Reporter: Dick King


For example, instead of saying the normal

  HOSTNAME="/1\.2\.3\.192/node0123\.hadoop-cluster\.megacorp\.com"

we might see the erroneous

  HOSTNAME="/1\.2\.3\.192/1\.2\.3\.197"

where the IP address of node0123.hadoop-cluster.megacorp.com is in fact 1.2.3.197 .

This is not a property of certain hosts.  In our cluster, most hosts are occasionally reported
in each of the two formats.
