Allen Wittenauer resolved MAPREDUCE-146.
----------------------------------------

    Resolution: Not a Problem

With split calculations moved and job submission changed, this is no longer a problem. Closing.

> In one scenario, job client uploaded the job split file and job jar onto the mapred system
directory but got killed before the actual job got submitted and/or before the job got known
to the JT. In such situations, the split and jar files are left as garbage as JT doesn't know
of the job yet. On a long running JT, this garbage can accumulate.
