Liang-Chi Hsieh closed SPARK-5907. ---------------------------------- Resolution: Duplicate > Selected column from DataFrame should not re-analyze logical plan > ----------------------------------------------------------------- > > Key: SPARK-5907 > URL: https://issues.apache.org/jira/browse/SPARK-5907 > Project: Spark > Issue Type: Bug > Components: SQL > Reporter: Liang-Chi Hsieh > > Currently, selecting a column from DataFrame wraps the original logical plan > with a Project. As the column is used, the logical plan will be analyzed > again. For some query plan, re-analyzing would side-effect that increases > expression id. So when accessing the column, column's expr and its analyzed > plan will point to different expressions. -- 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
