I follow the tutorial VerdictDB on Apache Spark and finally made it work. However, if I submit the example job twice, it will throw an [ERROR] AlreadyExistsException
ERROR metastore.RetryingHMSHandler: AlreadyExistsException(message:Database verdictdbtemp already exists)
but the code still got executed correctly. It seems there's no bad effect from having that exception. Maybe change it to WARNING?
WARNING
