Ronnie, It looks like you found out, the JobClient is only useful for connecting within the scope of the jobs you submit through it. If you use JobClient.getAllJobs(); it will only return jobs within the scope of that instance and not jobs that were sent by another application or through hadoops binary submit routine. It seems like a useful feature to provide in the future.

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. > ________________________________ > Ronnie Dove > OceanSync Hadoop Management Software > http://www.OceanSync.com >
