> 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.
