Interesting. Any intuition as to why slice can get the hanging resolved?

Yes. It is an unsupported expression in spark-rapids so falls back to cpu and injects columnartorow and rowtocolumnar transformations which do some batching that doesn't (but should after patching) happen otherwise.

Do we keep item number 5, 6 or replace with 1, 2?

Interesting. Didn't intend to change the numbers, will revert.

While we keep this here, do we need to remove it from gpu_cluster_spec.sh (the one without GPU ETL)?

Yes. Will delete there. Good catch.

Also adds db version as option to db benchmark script and a gpu only option (i.e. no spark rapids plugin).
Plus some other misc. updates (e.g. to logistic reg. notebooks, spark-rapids versions).
Includes a temporary patch till NVIDIA/spark-rapids#10770 is fixed.
