There was a problem hiding this comment.
This is a good start, but if you look at the JIRA, this exception won't actually echo back to the user the name they provided, which is bad form. I think you should capture the argument the user provided first then echo it back to them:
private val schedulingModeConf = conf.get("spark.scheduler.mode", "FIFO")
val schedulingMode: SchedulingMode = try {
SchedulingMode.withName(schedulingModeConf).toUpperCase)
} catch {
case e: java.util.NoSuchElementException =>
throw new SparkException(s"unrecognized spark.scheduler.mode: $schedulingModeConf")
}
Don't even bother re-sending the NoSuchElementException... it doesn't convey anything useful to the user.
…ave nicer error messages There are two improvements to Scheduler Mode: 1. Made the built in ones case insensitive (fair/FAIR, fifo/FIFO). 2. If an invalid mode is given we should print a better error message.

### What changes were proposed in this pull request? Task 198's quiet run, which apache#388 merged without: `VarkaSharedPrefixBenchmark` regenerated on the quiet laptop at both widths, a band from five repeats, and `PLAN_TASK_198.md` 6 scoring the three predictions. - **The computed-once prefix is admitted, and row 200 with it.** Sixty groups cost 2.7 times the default twelve on the wide run (2.5 narrow), and the default's repeated prefixes are at most about 40% of its time (33% narrow), above the 20% the admission asked for. It is a ceiling, since each extra group also reloads the column and runs its own loop. - **The cheap-tail cliff is decided per JVM run, not by grouping.** The same kernel ran fast in some runs and about sixty times slower in others; the one-group kernel was fast in all five band runs and slow in the regeneration's single run, and the pattern reverses at 128 bits. Row 209 now starts from the JVM's own evidence rather than timings, and the committed cheap-tail rows are marked as a slow-mode run. The branch also carries apache#428's fix, so that its quote check passes before apache#428 merges. ### Why are the changes needed? The admission check is the decision this task exists to make, and apache#388 merged before the quiet window. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? The canary passed before the run; the quote check and the Varka pre-commit checks pass. ### Was this patch authored or co-authored using generative AI tooling? Generated-by: Claude Code (Claude Opus 5.5)
