Description

For Apache Cassandra 5.0, sstableloader fails to load data into a table which has vector columns but still returns 0.

Important Observation:

When I tried the above bulkload, there was another table in my cassandra-cluster in which one of the columns was a UDT containing a vector type. After dropping that table and UDT, bulkload worked.
