----------------------------------
Summary: 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.
