Its doing this Tim: http://hbase.apache.org/xref/org/apache/hadoop/hbase/mapreduce/TableInputFormatBase.html#145 On the machine launching the job, its asking what the region location is. What is in .META. table? Names or IPs? If former, then its the resolve on the machine launching the job that is mangling it (DNS falls back to IP if problem figuring name). Can you mess w/ the DNS on the machine that is launching the job? See if you can find issue in its DNS (This is 0.90.X? If so, does its forward and back DNS give same answer? If 0.92.1, shouldn't matter). St.Ack
