Liang-Chi Hsieh created SPARK-14354: ---------------------------------------
Summary: Let Expand take name expressions and infer output attributes Key: SPARK-14354 URL: https://issues.apache.org/jira/browse/SPARK-14354 Project: Spark Issue Type: Improvement Components: SQL Reporter: Liang-Chi Hsieh Currently we create Expand operator by specifying projections (Seq[Seq[Expression]]) and its output. We allow Expand to reuse child operator's attributes and so make its contraints invalid. We should let it take name expressions and infer output itself. -- 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
