The failed unit test is unrelated to the change. And work fine locally.

@tasanuma @ayushtkn Please take a look. Thank you very much.

Merged. Thanks for your contribution, @tomscut, and thanks for reviewing it, @ferhui and @ayushtkn.

@tomscut I'd like to cherry-pick it to lower branches, but there are small conflicts. Could you create another PR for branch-3.3? The variable of name in TestFsDatasetImpl doesn't exist in branch-3.3.

Thank you for reminding me. I would love to do this and I will submit a separate PR later.

Hi @tasanuma , I submitted a PR #3666 for branch-3.3. Please help review it after the build. Thank you very much.
