This one is particularly interesting. The failure indicates a missing GPU metric:

2024-06-12 18:30:10,128 [Executor task launch worker for task 0.0 in stage 41.0 (TID 164)] ERROR org.apache.spark.executor.Executor - Exception in task 0.0 in stage 41.0 (TID 164)

I'm double checking to see if this fails in non-Spark-4 builds.

I've unassigned myself from this bug. This should be sorted out after the missing GPU metrics are addressed.

This passes now that the gpuDecodeTime errors have been resolved -- #11429
