[GitHub] [arrow-ballista] Dandandan commented on issue #353: Scheduler silently replaces `ParquetExec` with `EmptyExec` if data path is not correctly mounted in container

   I believe Spark / Presto / etc. commonly return an empty result when given a path/table without any files (on object storage). This makes sense for an empty table.
   
   Looking at the example though it shows an actual file that has been listed, so in that case I agree we should return an error.
