[jira] [Work logged] (MAPREDUCE-7360) Clean shared state pollution
to avoid flaky tests
[ https://issues.apache.org/jira/browse/MAPREDUCE-7360?focusedWorklogId=637245&page=com.atlassian.jira.plugin.system.issuetabpanels:worklog-tabpanel#worklog-637245 ]

Work Description: LALAYANG opened a new pull request #3300:
URL: https://github.com/apache/hadoop/pull/3300
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.
