Review Comment:
After add the test case to
[aggregate_with_roll_up.groovy](https://github.com/apache/doris/blob/master/regression-test/suites/nereids_rules_p0/mv/agg_with_roll_up/aggregate_with_roll_up.groovy)
you can run the command as following to re generate
aggregate_with_roll_up.out:
`./run-regression-test.sh --run -d nereids_rules_p0/mv/agg_with_roll_up -s
aggregate_with_roll_up -forceGenOut
`
see regresson-test detail in
[https://doris.apache.org/community/developer-guide/regression-testing](https://doris.apache.org/community/developer-guide/regression-testing)
