> The JobTracker Instrumentation API is currently sending JobTracker configuration to submitJob(conf, JobID) call.  Instead, this should be changed to submitJob(job.getJobConf(), JobID) to obtain job related configuration.  i.e., Chukwa could use this API to find out the job history file location.  In addition, the API should be public for general public to implement useful utilities to interface with this API.
