There was a problem hiding this comment.
I think this is kind of a follow-up to my #32947.
Looks good, but can you please adjust the title to describe what the PR does and not the issue?

### What changes were proposed in this pull request? If we call DataSourceV2ScanExecBase redact method from a thread that don't have a session in thread local we get an NPE. Getting stringRedactionPattern from conf could prevent this problem as conf checks if session is null or not. We also use this in DataSourceScanExec trait. https://github.com/apache/spark/blob/master/sql/core/src/main/scala/org/apache/spark/sql/execution/DataSourceScanExec.scala#L93-L95 ### Why are the changes needed? To prevent NPE when session is null. ### Does this PR introduce _any_ user-facing change? No ### How was this patch tested? Existing UTs. ### Was this patch authored or co-authored using generative AI tooling? No Closes apache#47419 from mikoszilard/SPARK-48946.
