Bikas Saha commented on TEZ-1372:
---------------------------------
If you want to override the sleep to something else then just override the
preWarmTezCode() method of PreWarmContainer. Its been made protected for this
reason.
waitTillReady() is a temporary. The plan is to allow the prewarm dag get killed
when the first real dag comes in. Because the intent of pre-warming is to use
the fallow time to do something useful and not come in the way of doing
something useful. waitTillReady() is a recommended method that should be called
before submitting any DAG (irrespective of prewarm) to ensure that the app
master is not busy running another dag. In your case, I am guessing you are
sure that App Master is not busy running another DAG already.
> Fix preWarm to work after recent API changes
