> Consider a scenario where a job was submitted to the M/R system and runs for a while.
Then say the JT is restarted, and before that the ACLs for the user are changed so that that
user can no longer submit jobs to that queue. Since the job could potentially be using resources
alloted to that queue and could be account for it, this might lead to accounting inconsistencies.
A suggestion is for the jobtracker to fail / kill this job.
