> VectorMapJoinOuterFilteredOperator does not currently support full outer joins but using the current Vectorizer logic it can be selected when a there is a filter involved. This can make queries fail with ClassCastException when their data and metadata in the VectorMapJoinOuterFilteredOperator do not match.
> The query attached demonstrates the issue and the log attached shows the java.lang.ClassCastException
