JobImpl.InitTransition.transition(JobImpl job,
JobEvent event)
Note that this transition method is called directly (and synchronously)
by MRAppMaster's init() method (i.e., no RPC, no thread-switching;
just plain sequential call within AM context), so we can trigger
modifications in AM state from here (at least, if AM is written that
way; MR version is). |

JobImpl.StartTransition.transition(JobImpl job,
JobEvent event)
This transition executes in the event-dispatcher thread, though it's
triggered in MRAppMaster's startJobs() method. |
