-----------------------------------
I can work on this one ...
> Improve metadata refresh
> ------------------------
>
> Key: SPARK-16311
> URL: https://issues.apache.org/jira/browse/SPARK-16311
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Reporter: Reynold Xin

> 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.
