[jira] [Created] (YARN-9479) Change String.equals to Objects.equals(String,String) to avoid possible NullPointerException

bd2019us created YARN-9479:
------------------------------

             Summary: Change String.equals to Objects.equals(String,String) to avoid possible NullPointerException
                 Key: YARN-9479
                 URL: https://issues.apache.org/jira/browse/YARN-9479
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: bd2019us


Hello,
I found that the String "queueName"  may have potential risk of 
NullPointerException since they are immediately used after initialization and there is no null checker. One recommended API is Objects.equals(String,String) which can avoid this exception.
