>
> MetricUtils.stringValue throws SparkException.internalError on unknown metric
> types, which is over-defensive for a UI rendering function. A crash at
> display time is worse than showing a degraded metric.
> Change to best-effort rendering: log at DEBUG level and format as '[unknown]
> N' with NumberFormat. This also enables downstream projects (Gluten, Comet)
> to define custom metric types without Spark core throwing.
