[jira] Updated: (MAPREDUCE-1222) [Mumak] We should not include
nodes with numeric ips in cluster topology.

New patch that excludes *well-formatted* ipv4 and ipv6 addresses. For ipv4 addresses, optimally allow each period preceded with double backslashes.

> 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.
