Apache Spark commented on SPARK-24165: -------------------------------------- User 'cloud-fan' has created a pull request for this issue: https://github.com/apache/spark/pull/21795 > UDF within when().otherwise() raises NullPointerException > --------------------------------------------------------- > > Key: SPARK-24165 > URL: https://issues.apache.org/jira/browse/SPARK-24165 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 2.2.0 > Reporter: Jingxuan Wang > Assignee: Marek Novotny > Priority: Major > Fix For: 2.4.0 > > > I have a UDF which takes java.sql.Timestamp and String as input column type > and returns an Array of (Seq[case class], Double) as output. Since some of > values in input columns can be nullable, I put the UDF inside a > when($input.isNull, null).otherwise(UDF) filter. Such function works well > when I test in spark shell. But running as a scala jar in spark-submit with > yarn cluster mode, it raised NullPointerException which points to the UDF > function. If I remove the when().otherwsie() condition, but put null check > inside the UDF, the function works without issue in spark-submit. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
