----------------------------------

Any chance of getting thread dumps ( as well as the logs ) to shed more light on this?

> I've seen a couple of instances where the Tez AM fails to complete the startup sequence.  It never gets around to registering with the ResourceManager, so the RM eventually times out the attempt and starts another.  The subsequent attempts do the same.  There are no indications in the logs that anything is wrong, rather it just seems to get stuck during startup then a bit over 10 minutes later is killed.
