Omkar Vinit Joshi commented on YARN-296:
----------------------------------------
I think we should get to the root of the problem here.. looking at the current
state transitions it looks like it is not possible for RMApp to get an
APP_ACCEPTED event and also it is not logical to get one...Adding the
transition will not be a good idea... I checked the rm restart code too and
there too it doesn't seem to be a problem...looks like either recent rm restart
changes fixed it or we are missing something..
