Same error I faced in my previous try, but no idea after some digging ...

Most likely it is due to scala version

First, thank you for the PR. I was able to compile your branch and it booted up and worked as expected, but the catalog registration did not work in the sense of adding a file catalog store. Looking in the Flink repo, it looks like they started instantiating the catalog manager differently. I don't know if the current flink shim structure is easily adapted to the new utilities added or something else needs to be done. If I get time this weekend I'd like to build off your work to see if we can get it working.

Hi, thanks for taking a look at it. I stumbled upon the same - was a bit too quick to celebrate after getting it up and running initially.
