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

             Summary: (findbugs) HE: Class defines equals() and uses Object.hashCode()
                 Key: HBASE-11463
                 URL: https://issues.apache.org/jira/browse/HBASE-11463
             Project: HBase
          Issue Type: Bug
            Reporter: Mike Drob
            Priority: Trivial


Findbugs warns that several classes define {{equals}} but not {{hashcode}}:

{noformat}
HE: Class defines equals() and uses Object.hashCode() (HE_EQUALS_USE_HASHCODE)

This class overrides equals(Object), but does not override hashCode(), and inherits the implementation
of hashCode() from java.lang.Object (which returns the identity hash code, an arbitrary value
assigned to the object by the VM).  Therefore, the class is very likely to violate the invariant
that equal objects must have equal hashcodes.
