Reynold Xin updated SPARK-16311:
--------------------------------
Description:
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.
was:
When the underlying file changes, it can be very confusing to users
The refresh command currently only works on metastore-based relations. It
should also work on temporary views/tables.
> Improve metadata refresh
