Junping Du commented on YARN-3866:
----------------------------------

The unit tests failed shouldn't be relevant to the patch. Most failed tests are 
common seen, the only one I didn't noticed before is 
TestCapacitySchedulerSurgicalPreemption which get tracked in YARN-5973. I 
verified locally to see if w/o the patch will affect these unit test failures. 
Here is the results:
|                 Tests                     | Without Patch | With Patch  |
| ----------------------------------------- |:-------------:| -----------:|
| TestCapacitySchedulerSurgicalPreemption   | FAILED        | FAILED      |
| TestAMAuthorization                       | FAILED        | FAILED      |
| TestFairScheduler                         | SUCCEED       | SUCCEED     |
| TestClientRMTokens                        | FAILED        | FAILED      |
| TestAMRMProxy                             | SUCCEED       | SUCCEED     |
| TestGetGroups                             | FAILED        | FAILED      | 


>From JACC report, we can see previous incompatible API issues involved in 
>YARN-3866 are resolved. The javac warning is just annoying because we are 
>adding back deprecated APIs for better compatibility.
I am planning to go ahead to commit the latest addendum patch before the end of 
today. Please comments if you have any concerns.
