5th JobTracker constructor (for simulator) uses outdated configs, duplicates code
---------------------------------------------------------------------------------
Key: MAPREDUCE-2024
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2024
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: jobtracker
Affects Versions: 0.22.0
Reporter: Greg Roelofs
Priority: Minor
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.
