Re: How Jobtracler stores tasktracker's information

Moving to mapreduce-user@, bcc common-user@. Please use project specific lists. 

Take a look at JobTracker.heartbeat -> *Scheduler.assignTasks.

After the scheduler 'assigns' tasks, the JT sends the corresponding 'LaunchTaskAction' to the TaskTracker.
