             Summary: Generalize f1score UDAF to support any Beta value
                 Key: HIVEMALL-132
                 URL: https://issues.apache.org/jira/browse/HIVEMALL-132
             Project: Hivemall
          Issue Type: Bug
            Reporter: Makoto Yui
            Priority: Minor


Currently, `f1score` only support 1.0 for β value of F-measure computation.

So, better to provide `f_measure` function that support any β value.
