Bikas Saha commented on TEZ-1372:
---------------------------------
Thanks for trying it out.
Why are you using MyDummyProcessor.class.getName() for the name? It does not
matter to us, unless you are trying to use it as some key look up that may be
better done via some API. Is QueryPreWarmProcessor deriving from the built-in
PreWarmProcessor? It may be better in some cases where PreWarmProcessor may be
able to initialize Tez lib classes. Also, PreWarmProcessor sleeps for some
time. This hack is useful when we dont get containers quickly enough from YARN.
Without the sleep the tasks might finish very quickly and container reuse may
kick in. So we end up not acquiring preWarmNumberOfContainers.
> Fix preWarm to work after recent API changes
