Review Comment:
> check `TestHiveCatalog#createTableAndVerifyOwner`, maybe that would be
helpful. why do you need to verify `ugi`, you mentioned that without the fix
test-case would fail
Thank you for your reply!
In the local file system, process users are used to read and write files,
not ugi users, so unit test will not failed.
No ugi related information will be left behind after
`IcebergInputFormat.getSplits` for subsequent inspection.
