Link to issue: [https://issues.apache.org/jira/browse/MAPREDUCE-7360](https://issues.apache.org/jira/browse/MAPREDUCE-7360) ## What is the purpose of this change This PR is to clean shared state pollution between tests: ``` Test1: org.apache.hadoop.mapreduce.v2.app.TestJobEndNotifier.testNotificationOnLastRetryShutdownWithRuntimeException Test2: org.apache.hadoop.mapreduce.v2.app.TestMRAppMaster.testMRAppMasterShutDownJob ``` - Test1 can pollute the shared state with Test2, which can lead Test2 to fail after running Test1. - It may be better to clean state pollutions so that some other tests won't fail in the future due to the shared state polluted by this test. ## Reproduce test failure First run Test1, then run Test2 in the same JVM ## Expected result The tests should run successfully when multiple tests that use this state are run in the same JVM. ## Actual result Run Test1 and Test2, Test2 fails: ``` [ERROR] TestMRAppMaster.testMRAppMasterShutDownJob:530 Expected shutDownJob to exit with status code of 0. expected:<0> but was:<1> ``` ## Fix Reset FirstExitException at the start of Test2 to clean the pollution from Test1. -- This is an automated message from the Apache Git Service.
