Hi, Little confused about where JNI comes in here (you mentioned this in your original email). Also, where do you want to get the information for the hadoop job ? Is it in a program that is submitting a job, or some sort of monitoring application that is monitoring jobs submitted to a cluster by others ? I think some of this information will drive an answer.
FWIW, JobID.forName(job_id_as_string) would give you a handle to a JobID tied to a job.
