>         Environment: I test it locally and on YARN in cluster mode.

> Do not work with {{foreach}} or {{foreachPartition actions.}}
> {{This is due to }}QueryExecutionListener functions do not trigger on queries whose action is {{foreach}} or {{{}foreachPartition{}}}.
> But the Spark GUI SQL tab sees this query as SQL query and shows its query plans and etc.
> here is the code to reproduce it:
