Review Comment:
   @itholic Yes, thank you. I actually noticed that there's already a test 
present for this error in RateStreamProviderSuite.scala:
   
https://github.com/apache/spark/blob/edafe266144c5c70852491fef9bb6907a001b286/sql/core/src/test/scala/org/apache/spark/sql/execution/streaming/sources/RateStreamProviderSuite.scala#L217-L237
   
   I'm not sure if it makes sense to move it or do anything more at all with 
this error, what do you think?
