>
> After migrating to Hudi's own Relation impls, we unfortunately broke off some
> of the optimizations that Spark apply exclusively for `HadoopFsRelation`.
>
> While these optimizations could be perfectly implemented for any
> `FileRelation`, Spark is unfortunately predicating them on usage of
> HadoopFsRelation, therefore making them non-applicable to any of the Hudi's
> relations.
> Proper longterm solutions would be fixing this in Spark and could be either
> of:
> # Generalizing such optimizations to any `FileRelation`
> # Making `HadoopFsRelation` extensible (making it non-case class)
