Apache Spark reassigned SPARK-9397:
-----------------------------------
Assignee: Apache Spark (was: Aaron Davidson)
> DataFrame should provide an API to find source data files if applicable
> -----------------------------------------------------------------------
>
> Key: SPARK-9397
> URL: https://issues.apache.org/jira/browse/SPARK-9397
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Reporter: Aaron Davidson
> Assignee: Apache Spark
> Priority: Critical
>
> Certain applications would benefit from being able to inspect DataFrames that
> are straightforwardly produced by data sources that stem from files, and find
> out their source data. For example, one might want to display to a user the
> size of the data underlying a table, or to copy or mutate it.
> Currently, there is not a good way to get this information in a public API.
