> When the underlying file changes, it can be very confusing to users when they see a FileNotFoundException. It would be great to do the following:
> (1) Append a message to the FileNotFoundException that a workaround is to do explicitly metadata refresh.
> (2) Make metadata refresh work on temporary tables/views.
> (3) Make metadata refresh work on Datasets/DataFrames, by introducing a Dataset.refresh() method.
