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

             Summary: Vectorization: different results between MR and Tez for aggregation
functions (variance, var_pop, var_samp, std, stddev, etc)
                 Key: HIVE-8063
                 URL: https://issues.apache.org/jira/browse/HIVE-8063
             Project: Hive
          Issue Type: Bug
            Reporter: Matt McCline
            Assignee: Matt McCline
            Priority: Critical



When running vectorized_timestamp_funcs.q with aggregation functions (listed in title), the
results were 0 on Tez and non-zero on MR.  The aggregatesDefinition table in VectorizationContext.java
currently disallows timestamp and date for those functions.
