Subject [jira] Commented: (MAPREDUCE-2024) 5th JobTracker constructor (for simulator) uses outdated configs, duplicates code
Date Fri, 03 Sep 2010 08:29:33 GMT

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.
