Description
When the JobTracker is instantiated, it starts listening on its RPC interfaces before its startup is complete (ie the constructor is finished executing). Because of this, jt.taskScheduler.taskTrackerManager can be null when the JT receives a heartbeat from a TT. This throws the JT/TT pair into a tight infinite loop (HADOOP-5761)
