[jira] [Commented] (SPARK-21896) Stack Overflow when window function nested inside aggregate function

["Anton Okolnychyi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-21896?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16151555#comment-16151555 ] 

Anton Okolnychyi commented on SPARK-21896:
------------------------------------------

The root cause of this issue is the inability of {{ExtractWindowExpressions}} to handle aggregations defined directly on top of window expressions (e.g., {{df.groupBy().agg(max(rank().over(window)))}}). The first place that has to be updated is {{ExtractWindowExpressions#extract}} and the second one is {{ExtractWindowExpressions#apply}} (only the aggregation case). The former does not extract present window expressions from aggregate functions (lines 1771-1774 in Analyzer) while the latter does not handle cases when aggregations should be computed on top of window computations (lines 1877-1888 in Analyzer).

I did not dive too much into the code, but it seems like {{ExtractWindowExpressions}} does not assume such definitions as {{df.groupBy().agg(max(rank().over(window)))}}. The question is if {{ExtractWindowExpressions}} should be extended/fixed to handle this case as well or it is by design and some analysis exception should be thrown.

As it is mentioned in the ticket description, {{df.select(rank().over(window).alias("rank")).agg(max("rank"))}} works fine.

>             Project: Spark
>          Issue Type: Bug
>          Components: PySpark, SQL
>    Affects Versions: 2.1.0, 2.2.0
>            Reporter: Luyao Yang
>            Priority: Minor
>
> A minimal example: with the following simple test data
> {noformat}
> >>> df = spark.createDataFrame([(1, 2), (1, 3), (2, 4)], ['a', 'b'])
> >>> df.show()
> +---+---+
> |  a|  b|
> +---+---+
> |  1|  2|
> |  1|  3|
> |  2|  4|
> +---+---+
> {noformat}
> This works: 
> {noformat}
> >>> w = Window().orderBy('b')
> >>> result = (df.select(F.rank().over(w).alias('rk'))
> ...            .groupby()
> ...            .agg(F.max('rk'))
> ...          )
> >>> result.show()
> +-------+
> |max(rk)|
> +-------+
> |      3|
> +-------+
> {noformat}
> But this equivalent gives an error. Note that the error is thrown right when the operation is defined, not when an action is called later:
> {noformat}
> >>> result = (df.groupby()
> ...            .agg(F.max(F.rank().over(w)))
> ...          )
