Jorge Machado updated SPARK-24401:
----------------------------------
Attachment: (was: testDF.parquet)
> Aggreate on Decimal Types does not work
> ---------------------------------------
>
> Key: SPARK-24401
> URL: https://issues.apache.org/jira/browse/SPARK-24401
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.2.0, 2.3.0
> Reporter: Jorge Machado
> Priority: Major
>
> Hi,
> I think I found a really ugly bug in spark when performing aggregations with
> Decimals
> To reproduce:
>
> {code:java}
> val df = spark.read.parquet("attached file")
> val first_agg = fact_df.groupBy("id1", "id2",
> "start_date").agg(mean("projection_factor").alias("projection_factor"))
> first_agg.show
> val second_agg =
> first_agg.groupBy("id1","id2").agg(max("projection_factor").alias("maxf"),
> min("projection_factor").alias("minf"))
> second_agg.show
> {code}
> First aggregation works fine the second aggregation seems to be summing
> instead of max value. I tried with spark 2.2.0 and 2.3.0 same problem.
