Chris Douglas updated HADOOP-3728:
----------------------------------
Attachment: 3728-0.patch
We could avoid writing a file at all. It looks like the input is used only to
control the number of sleeps each mapper should observe, so we can write a
RecordReader that emits the expected number of records to each map.
> Cannot run more than one instance of examples.SleepJob at the same time.
