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.
Thanks, pete
Seems to me something that should be remotely available and visible via
JMX...always good to use. Absolute time info, if sent as a time_t long
should be in UTC to avoid confusion when talking to servers in different
time zones...
