Hi
@Lior Resisi, welcome back!
1. We stepped away from lakeFS OutputCommitter, and are back to advising the use of default committers (FileOutputCommitter for lakeFSFS, latest magic for S3A).
2. lakeFSFS (the Hadoop filesystem) requires only Hadoop compatibility, and should work with Hadoop 3.x. It should work with your hadoop-aws. That said, I don't think we regularly test it with 3.5; could you open an issue, please?
3.
Spark metadata client should "just work", but I would definitely open an issue there before
4. Are you still running on-prem Spark versions, or is it managed? Managed versions can have a
lot of cruft that may cause issues.
