>             Project: Apache Ozone
>          Issue Type: Sub-task
>    Affects Versions: 1.1.0

> I noticed a mock in this test as follows:
> {code:java}
> Mockito.doReturn(null).when(mockBm).getBucketInfo(null, null);{code}
> But in reality the behavior would be different as per the source code:
> {code:java}
> @Override
> public OmBucketInfo getBucketInfo(String volumeName, String bucketName)
>  throws IOException {
>  Preconditions.checkNotNull(volumeName);
>  Preconditions.checkNotNull(bucketName);{code}
>  
> Due to the above preconditions, null is not allowed and it will throw NPE.
> Some one who familiar with this code can confirm why we added this differed mock behavior.
