### Describe the issue this Pull Request addresses issue: #20111 part of #20064 Stacked on #20112, review that first. Schema-on-read reads and the CDC read of a version 6 MERGE_ON_READ table still pay per-task executor overhead on master, so their guards cannot go into #20112. ### Summary and Changelog Adds those reads to `TestSparkReadExecutorFootprint`: a schema-on-read snapshot read of version 6 and current COPY_ON_WRITE and MERGE_ON_READ tables must not touch `.hoodie` from the tasks, and the version 6 MERGE_ON_READ CDC read gets the `.hoodie` and task size guards. On master the 4 schema-on-read rows fail (tasks look up the schema history in `.hoodie` for every file, fixed by #20085) and the 2 version 6 MERGE_ON_READ CDC rows fail on the driver (fixed by #20071). Merge after both. ### Impact Test only. ### Risk Level none ### Documentation Update none ### Contributor's checklist - [ ] Read through [contributor's guide](https://hudi.apache.org/contribute/how-to-contribute) - [ ] Enough context is provided in the sections above - [ ] Adequate tests were added if applicable -- This is an automated message from the Apache Git Service.
