I see there are some test failures for iceberg product tests(with kerberos and impersonation enabled). I haven't had a chance to look at all the changes yet but I suspect this might be because the iceberg library is probably not able to find the relevant hadoop configurations. Let's verify whether the config is getting passed as expected after the removal of custom FileIO in this PR.
