Tsz Wo Nicholas Sze created HDFS-9729:
-----------------------------------------

             Summary: Use null to replace DataNode.EMPTY_DEL_HINT
                 Key: HDFS-9729
                 URL: https://issues.apache.org/jira/browse/HDFS-9729
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: datanode
            Reporter: Tsz Wo Nicholas Sze
            Assignee: Tsz Wo Nicholas Sze
            Priority: Minor


When a delete-hint is unavailable, the current code may use null or DataNode.EMPTY_DEL_HINT as a default value.  Let's uniformly use null for an empty delele-hint.
