---------------------------------------------
Summary: ClassCastException caused by wrong Vectorized operator
selection
Key: HIVE-22505
URL: https://issues.apache.org/jira/browse/HIVE-22505
Project: Hive
Issue Type: Bug
Components: Vectorization
Reporter: Panagiotis Garefalakis
Assignee: Panagiotis Garefalakis
Attachments: query_error.out, query_vector_explain.out
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
