lujie updated YARN-7663:
------------------------
Attachment: YARN-7663_5.patch
Hi:
{code:java}
Rather than calling createNewTestApp then throwing away the results, it would
be cleaner to extend createNewTestApp to take a boolean parameter specifying
whether to create an app with invalid state transition detection or without.
Alternatively you could factor out the rmContext, scheduler, and conf setup
from createNewTestApp so the test can leverage it without needing to do all the
other, unrelated stuff in createNewTestApp.
{code}
After I implement both of the two plans, I perform the second plan because it
will add less code and more cleaner. In the new patch , I factor out the
unrelated arguments that passed(set them to null) to constructed function of
RMAppImpl as more as possible.
