Subject [GitHub] incubator-hivemall issue #107: [HIVEMALL-132] Generalize f1score UDAF to sup...
Date Tue, 29 Aug 2017 04:11:05 GMT
Github user nzw0301 commented on the issue:

    https://github.com/apache/incubator-hivemall/pull/107
  
    But I found another issue for f1score and fmeasure.
    
    Both function cannot work on `EMR v5.8.0`
    
    ```sql
    hive> select f1score(array(1), array(1));
    FAILED: IllegalArgumentException Size requested for unknown type: org.apache.hadoop.hive.ql.exec.UDAFEvaluator
    ```
    
    ```sql
    hive> select fmeasure(array(1), array(1));
    FAILED: IllegalArgumentException Size requested for unknown type: java.lang.String
    ```
    
    However, they can work on `EMR v5.0.0`.
    I don't know why the failures occur on newer EMR.
