hi all, I want to figure out, from a client of Hadoop cluster, the statuses of jobs that are currently running on the cluster. I need it in order to prevent the client from submitting certain jobs to the cluster, when some certain jobs are already running on the cluster. I know to recognize my jobs - by their name.
How do I do it? I saw the JobTracker code in jobtracker.jsp. I would be happy to use its 'runningJobs' method. The thing is that in the JSP, which is executed on the cluster (master), we get hold of the JobTracker from the application context. Is it safe to instantiate my own JobTracker, given the right conf, from the client? thanks ShlomiJ
