I'm looking for the actual #of seconds since (or absolute time) the job tracker was ready to start accepting jobs.
I'm writing a utility to (attempt :)) more robustly run hadoop jobs and one thing I want to detect is if the JobTracker has gone down while a job that failed was running. Since the script will also sleep and poll the job tracker till it comes back up (or connectivity is restored), when I finally contact the job tracker, I want to know how long its been running. So, knowing whether the JT is initializing or not is useful, but also the actual time it was ready.
