Eric Yang commented on HADOOP-4818:
-----------------------------------

Owen and Arun thinks it is too open for outside of hadoop community to inject code at this
level.

> 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.
