Herman van Hovell commented on SPARK-18172:
-------------------------------------------
This is different from SPARK-18300, this is not a case where foldable
propagation is an issue. The thing is that we fixed a lot of these issues
recently, so I am not sure which one fixed this one.
I am closing this one, please re-open if you hit this again.
> AnalysisException in first/last during aggregation
> --------------------------------------------------
>
> Key: SPARK-18172
> URL: https://issues.apache.org/jira/browse/SPARK-18172
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.0.1
> Reporter: Emlyn Corrin
> Fix For: 2.0.2
>
>
> Since Spark 2.0.1, the following pyspark snippet fails with
> {{AnalysisException: The second argument of First should be a boolean
> literal}} (but it's not restricted to Python, similar code with in Java fails
> in the same way).
> It worked in Spark 2.0.0, so I believe it may be related to the fix for
> SPARK-16648.
> {code}
> from pyspark.sql import functions as F
> ds = spark.createDataFrame(sc.parallelize([[1, 1, 2], [1, 2, 3], [1, 3, 4]]))
> ds.groupBy(ds._1).agg(F.first(ds._2), F.countDistinct(ds._2),
> F.countDistinct(ds._2, ds._3)).show()
> {code}
> It works if any of the three arguments to {{.agg}} is removed.
> The stack trace is:
