Zhong Wang created SPARK-13337: ---------------------------------- Summary: DataFrame join-on-columns function should support null-safe equal Key: SPARK-13337 URL: https://issues.apache.org/jira/browse/SPARK-13337 Project: Spark Issue Type: Improvement Affects Versions: 1.6.0 Reporter: Zhong Wang Priority: Minor
Currently, the join-on-columns function: <code> def join(right: DataFrame, usingColumns: Seq[String], joinType: String): DataFrame <code> performs a null-insafe join. It would be great if there is an option for null-safe join. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
