Apache Spark commented on SPARK-11080: -------------------------------------- User 'JoshRosen' has created a pull request for this issue: https://github.com/apache/spark/pull/9093 > NamedExpression.newExprId should only be called on driver > --------------------------------------------------------- > > Key: SPARK-11080 > URL: https://issues.apache.org/jira/browse/SPARK-11080 > Project: Spark > Issue Type: Bug > Components: SQL > Reporter: Josh Rosen > Assignee: Josh Rosen > > My understanding of {{NamedExpression.newExprId}} is that it is only intended > to be called on the driver. If it is called on executors, then this may lead > to scenarios where the same expression id is re-used in two different > NamedExpressions. > More generally, I think that calling {{NamedExpression.newExprId}} within > tasks may be an indicator of potential attribute binding bugs. Therefore, I > think that we should prevent {{NamedExpression.newExprId}} from being called > inside of tasks by throwing an exception when such calls occur. -- 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
