Hong Tang commented on MAPREDUCE-1222: -------------------------------------- @dick, thanks for the help. The solution is more complex than I would like to have in solving the trivial problem this jira represents. I suggest we go for a less efficient, but more direct and thus easier-to-maintain solution: unescaping the dots and rely on java's IPv4 or IPv6 parsing code. > [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 > Affects Versions: 0.21.0, 0.22.0 > Reporter: Hong Tang > Assignee: Hong Tang > Fix For: 0.21.0, 0.22.0 > > Attachments: IPv6-predicate.patch, mapreduce-1222-20091119.patch, > mapreduce-1222-20091121.patch > > > Rumen infers cluster topology by parsing input split locations from job > history logs.
