Have you test this feature with HDFS, or will it introduce regression for
other workload?
If not, we should turn it on by default, or even don't have this config

If your project is set up for it, you can reply to this email and have your
reply appear on GitHub as well. If your project does not have this feature
enabled and wishes so, or if the feature is enabled but not working, please

with INFRA.
