> 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
