Review Comment:
Thank you for your comment!
We removed this part of the code based on the suggestion from Mockito, which
indicated that this code was not called in the test and recommended its removal.
The error messages are as follows:
```
org.mockito.exceptions.misusing.UnnecessaryStubbingException:
Unnecessary stubbings detected.
Clean & maintainable test code requires zero unnecessary code.
Following stubbings are unnecessary (click to navigate to relevant line of
code):
1. -> at
org.apache.hadoop.mapred.TestTaskAttemptListenerImpl.testGetMapCompletionEvents(TestTaskAttemptListenerImpl.java:264)
2. -> at
org.apache.hadoop.mapred.TestTaskAttemptListenerImpl.testGetMapCompletionEvents(TestTaskAttemptListenerImpl.java:266)
3. -> at
org.apache.hadoop.mapred.TestTaskAttemptListenerImpl.testGetMapCompletionEvents(TestTaskAttemptListenerImpl.java:268)
Please remove unnecessary stubbings or use 'lenient' strictness. More info:
javadoc for UnnecessaryStubbingException class.
