lujie updated YARN-7663:
------------------------
Attachment: YARN-7663_3.patch
After reading Jason Lowe useful suggestion. I change the unit test and attach
the new patch .
In this patch ,I do three three things: 1. add empty protected
methodon:onInvalidStateTransition, and add its callsite in the code block that
RMAppImpl handle InvalidStateTransition2.create a new final class
RMAppImplForTest which override onInvalidStateTransition.In createNewTestApp,
create RMAppImplForTest object instead of RMAppImpl. 3. fix this bug by
ignore the event
But there are another two InvalidStateTransition while
testing:1.testAppAcceptedFailed:APP_ACCEPTED at state
2.testAppRunningFailed:ACCEPTED,APP_UPDATE_SAVED at state KILLED.
These two InvalidStateTransition maybe bugs in RMAppimpl, or may be bugs in
TestRMAppTransitions. ishould be better to defer that to another JIRA?
Or can we just ignore the event without test, just as [link
