Hi @NJU-cerulean. Thanks for your PR.

I'm waiting for a fluid-cloudnative member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

The documentation can be improved for accuracy. The Du method specifically executes the alluxio fs du -s command. Also, the DATA_NUM test case verifies the handling of a mismatched number of fields (columns) in the command output, rather than the values of the data itself.
