> Add deleteWithJob hook to internal commit protocol API

> Key: SPARK-19183

> Project: Spark

> Components: SQL
> Reporter: Eric Liang

> Currently in SQL we implement overwrites by calling fs.delete() directly on
> the original data. This is not ideal since we the original files end up
> deleted even if the job aborts. We should extend the commit protocol to allow
> file overwrites to be managed as well.
