How to config a Gravitino Catalog and a Trino For Querying above multiple Hadoop Systems

[theoryxu]

Hi Fellows

I read the docs and found that: https://datastrato.ai/docs/0.4.0/trino-connector/catalog-hive#hdfs-config-and-permissions

So, how do I configure a Gravitino Catalog and a Trino For querying above multiple Hadoop Systems?

Is there any advice, or do some docs provide more details?

Thanks

@theoryxu Thank you for the question.
In Trinno docs hdfs-username-and-permissions.
We can solve these problems with the ·Kerberos solution·.. The Gravitino 0.4 version does not support it for now. This issue will be resolved in future versions.

Would creating multiple catalogs (one per system) and then doing cross catalog queries work?
