[Mumak] We should not include nodes with numeric ips in cluster topology.
-------------------------------------------------------------------------

                 Key: MAPREDUCE-1222
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1222
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: contrib/mumak
            Reporter: Hong Tang


Rumen infers cluster topology by parsing input split locations from job history logs. Due
to HDFS-778, a cluster node may appear both as a numeric ip or as a host name in job history
logs. We should exclude nodes appeared as numeric ips in cluster toplogy when we run mumak
until a solution is found so that numeric ips would never appear in input split locations.
