Review comment:
       I also thought about update the following
   
https://github.com/apache/spark/blob/8659ec554fe1993fcaf2ec4d1c4745205bddec7d/sql/core/src/main/scala/org/apache/spark/sql/execution/datasources/DataSource.scala#L575
   
   to
   
   ```
   val allPaths = 
caseInsensitiveOptions.get("path").map(Seq(_)).getOrElse(paths)
   ```
   , but it looked like a risky change (e.g., there is no good place for 
assert, etc.).
