Hong Tang commented on MAPREDUCE-2024:
--------------------------------------

Is this a duplicate of MAPREDUCE-1001? If so, we probably should keep only one.

> The fifth JobTracker constructor (JobTracker(final JobConf conf, Clock clock, boolean ignoredForSimulation)) still uses the old "mapred.*" config settings and appears to duplicate much of the code in the fourth (main) ctor.  It should be modernized and, ideally, share as much code as possible with the main one in order to minimize simulation drift and the potential for config errors.
