> I was running a mapreduce job (via Hive) against HBase, and noticed that I wasn't getting
any locality (the input split location and the task tracker machine in the job tracker UI
were always different, and "Rack-local map tasks" in the job counters was 0).
> I tracked this down to a discrepancy in the way hostnames were being compared.
> The task tracker detail had a Host like
> /f/s/1.2.3.4/h.s.f.com.
> (with trailing dot)
> But the Input Split Location had
> /f/s/1.2.3.4/h.s.f.com
> (without trailing dot)
