@HyukjinKwon I've raised this PR as a WIP till I incorporate your comments. I had some doubts regarding the tests in pivot.sql and was hoping you could clear it for me.

While porting 'pivot.sql', I ran the command below on the original sql and it fails when running for configs spark.sql.codegen.wholeStage=true,spark.sql.codegen.factoryMode=CODEGEN_ONLY

build/sbt "sql/test-only *SQLQueryTestSuite -- -z pivot.sql"

On inspection it seems like there is some discrepancy while handling the null values when passing through the udf. For Scala its expecting null, for Python its expecting None but the golden files contains nan. Thus the match is failing.

This error persists in the port also. As per the guide, I tried looking for a related Jira but couldn't find one, so I thought I'd run this by you first before creating one.

Stacktrace:

add to whitelist

HyukjinKwon · 2019-07-12T02:06:03Z

The null <> None issue should be due to different results from Python and Scala side. I described a bit of context in the PR description of #25069 for now ..

HyukjinKwon · 2019-07-12T02:08:38Z

I discussed similar issue at #25098 with @skonto FWIW.

@HyukjinKwon Thanks for your review comments, I've replied to them.

I feel the suggested workaround(this and this) will not work in this case as certain udf's like sum return null if aggregated on empty datasets (SPARK-20346).

As per the guide in SPARK-27921 , do you suggest I create a separate Jira for this and comment the problematic test cases for now ?

I can test it by myself but I thought you know the results - just out of curiosity, what do we get if we do FOR udf(course)?

FOR udf(course) in line 29 will result in a org.apache.spark.sql.catalyst.parser.ParseException
