--------------------------------

             Summary: 
o.a.h.hdfs.protocol.SnapshotDiffReport$DiffReportEntry$hashCode inconsistent 
with equals
                 Key: HDFS-9573
                 URL: https://issues.apache.org/jira/browse/HDFS-9573
             Project: Hadoop HDFS
          Issue Type: Bug
            Reporter: John Zhuge
            Assignee: John Zhuge
            Priority: Minor


DiffReportEntry.equals() uses field "type", but DiffReportEntry.hashCode() 
doesn't. This breaks the rules on equals and hashCode:
* if a class overrides equals, it must override hashCode
* when they are both overridden, equals and hashCode must use the same set of 
fields
