Weiluo Ren created SPARK-18170: ---------------------------------- Summary: Confusing error message when using rangeBetween without specifying an "orderBy" Key: SPARK-18170 URL: https://issues.apache.org/jira/browse/SPARK-18170 Project: Spark Issue Type: Bug Components: SQL Reporter: Weiluo Ren Priority: Minor
{code} spark.range(1,3).select(sum('id) over Window.rangeBetween(0,1)).show {code} throws runtime exception: {code} Non-Zero range offsets are not supported for windows with multiple order expressions. {code} which is confusing in this case because we don't have any order expression here. How about add a check on {code} orderSpec.isEmpty {code} at https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/window/WindowExec.scala#L141 and throw an exception saying "no order expressions is specified"? -- 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
