[QUESTION] Spark versions compatibility for operator version v1beta2-1.6.x-3.5.0

• ✋ I have searched the open/closed issues and my issue is not listed.

Please describe your question here

As per documentation base spark version for operator version v1beta2-1.6.x-3.5.0 is 3.5.0.
What is mean by base spark version here ?
We are using spark 3.4.1 (cant upgrade to 3.5.0 as of now), we just tested once example application with operator version v1beta2-1.6.x-3.5.0 and spark version 3..4.1. So far no issues. Does it mean , operator operator version v1beta2-1.6.x-3.5.0 supports spark 3.4.1 also ?
If this is not recommended , which operator version we should use ?

Provide a link to the example/module related to the question

@kraj007 In Spark operator, it will use spark-submit script to submit spark applications to kubernetes, and this spark-submit script comes from Spark 3.5.0 (for operator version v1beta2-1.6.x-3.5.0). In most cases, it will be fine, since the spark-submit changes slightly between v3.4.x and v3.5.x.
