Thinks @hawk9821 . Good job. I think your e2e case needs to be added to the case of multi-parallelism, the current case is all single parallelism. In this way, we can effectively verify whether the dynamic bucketing will change depending on the degree of parallelism of the job. Also, I think you should check the bucket count in every case instead of making a separate case. In addition, each of your cases should verify that the dynamic-bucket.target-row-num argument works as expected.

LGTM if ci passes. Thanks @hawk9821
