This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
We don't need to add v003tov004.sh because the change (removal of dclocal_read_repair_chance config) is in table metadata which gets handled seemlessly within cassandra upgrade when users upgrade their cassandra cluster from v3.11 to v4.0. Refactor cassandra integration tests to run on both cassandra v3.11 and v4.0. Signed-off-by: Ashmita Bohara <ashmita.bohara152@gmail.com>
