Summary: Subquery should not cause NPE when eliminating subexpression Key: SPARK-29239 URL: https://issues.apache.org/jira/browse/SPARK-29239 Project: Spark Issue Type: Bug Components: SQL Affects Versions: 3.0.0 Reporter: Liang-Chi Hsieh Subexpression elimination can possibly cause NPE when applying on execution subquery expression like ScalarSubquery. It is because PlanExpression wraps query plan. To compare query plan on executor when eliminating subexpression, can cause unexpected error, like NPE when accessing transient fields. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
