Hyukjin Kwon updated SPARK-19854:
---------------------------------
Labels: bulk-closed (was: )
> Refactor file partitioning strategy to make it easier to extend / unit test
> ---------------------------------------------------------------------------
>
> Key: SPARK-19854
> URL: https://issues.apache.org/jira/browse/SPARK-19854
> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 2.1.0
> Reporter: Reynold Xin
> Assignee: Reynold Xin
> Priority: Major
> Labels: bulk-closed
>
> The way we currently do file partitioning strategy is hard coded in
> FileSourceScanExec. This is not ideal for two reasons:
> 1. It is difficult to unit test the default strategy. In order to test this,
> we need to do almost end-to-end tests by creating actual files on the file
> system.
> 2. It is difficult to experiment with different partitioning strategies
> without adding a lot of if branches.
> The goal of this story is to create an internal interface for this so we can
> make this pluggable for both better testing and experimentation.
