> Components: mapreduce

> Reporter: Robert Dyer

>
> TableInputFormatBase.reverseDNS makes a call to
> org.apache.hadoop.net.DNS.reverseDns which (at least in Hadoop 1.0.4) returns
> a PTR record. PTR records contain a trailing period, which then shows up in
> the input split location causing the JobTracker to incorrectly match map jobs
> to data-local map slots.
