Connect Trino to a local S3 with bucket at root path

[crtvmn]

Hello, I'm trying to connect Trino to a local S3 in a Kubernetes cluster. The connection works with Hive 4.0.1 but when I try to read data in my S3 cluster (located at the S3 root path in the /test/ bucket), I got the following error:

[trino@trino-coordinator-bd5c6ccc6-7kvnp /]$ trino --debug
trino> CREATE TABLE hive.default.test (
    ->         name varchar,
    ->         description varchar,
    ->         address varchar,
    ->         job varchar
    ->     )
    ->     WITH (
    ->         external_location = 's3a://test/',
    ->         format = 'JSON'
    ->     );

I didn't have this error with Hive 3.x.

I found this issue in the Hive Jira https://issues.apache.org/jira/plugins/servlet/mobile#issue/HIVE-25912 (and Github changes apache/hive#3009) but we can not contact them with "discussion" or "issue" in their Github repository.

I'm asking if you have any information on this problem or maybe an alternative with Hive or another component.

Thank you for your help!
