JobTracker API Hooks

Hello,

Is it possible to connect to an already running JobTracker via socket through the Hadoop Java API?  I see that there is a startTracker method but nothing to establish a connection/hook into a currently running JobTracker, that might of been launched prior to an application connecting.  I know that I can use JobClient to assist with tracking jobs that I submit through my application but I was interested in monitoring all job statuses that were launched by other applications or users that launch jobs independently through the Hadoop command line.

Thanks in advance.

Moving it to mapreduce-user.

Ronnie,
Is jobclient.getalljobs() something that you are looking for?

thanks
