## Comments

22/Dec/21 01:30;guoyihua;The implementation is done: [https://github.com/codope/trino/pull/3]

Currently, HBase 1.2.3 used by Hudi is not compatible with Java 11 (required for Trino) when querying the table with bootstrap file format: `Caused by: java.lang.RuntimeException: Unexpected version format: 11.0.13`

01/Nov/23 14:25;codope;Reopened as we can't use `FileStatus`. After [https://github.com/trinodb/trino/pull/17392], Hadoop libs have been removed from the connector. So, the above implementation won't work.;;;

Research direction

Start by reviewing the implementation linked in the comment and the effects of trinodb/trino#17392, which removed Hadoop libraries from the connector. Inspect how bootstrap file format handling can work without FileStatus; done means querying Hudi tables with bootstrap file splits works on Java 11 without the removed Hadoop dependency.
