Abhishek Kapoor commented on YARN-369:
--------------------------------------
It looks like the respective change to fix the issue will effect unit test
cases where allocate call is made prior to registerApplicationMaster. That
include below mentioned Test case
TestRMRestart.
AMResponse amResponse = am1.allocate(new ArrayList<ResourceRequest>(),
new ArrayList<ContainerId>());
Assert.assertTrue(amResponse.getReboot());
Any suggestion is welcome.
> Handle ( or throw a proper error when receiving) status updates from
> application masters that have not registered
