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

             Summary: pig version of HyperLogLog estimator should be Algebraic and use combiners
                 Key: DATAFU-91
                 URL: https://issues.apache.org/jira/browse/DATAFU-91
             Project: DataFu
          Issue Type: Bug
    Affects Versions: 1.3.0
            Reporter: Ido Hadanny
            Priority: Minor


Matt: I don't remember if there was a particular reason I didn't implement this as AlgebraicEvalFunc.
It seems like it could be. I believe the Java MapReduce version leverages the combiner. If
you want to try making this Algebraic we would be happy to accept a patch :)
