    Description

      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
