5th JobTracker constructor (for simulator) uses outdated configs, duplicates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.
