> (Dataset-oriented) API evolution in Spark 2.0
> ---------------------------------------------
>
> Key: SPARK-13485
> URL: https://issues.apache.org/jira/browse/SPARK-13485
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Reporter: Reynold Xin
> Assignee: Reynold Xin
> Priority: Blocker
> Labels: releasenotes
> Fix For: 2.0.0

> Attachments: API Evolution in Spark 2.0.pdf
>
>
> As part of Spark 2.0, we want to create a stable API foundation for Dataset
> to become the main user-facing API in Spark. This ticket tracks various tasks
> related to that.
> The main high level changes are:
> 1. Merge Dataset/DataFrame
> 2. Create a more natural entry point for Dataset (SQLContext/HiveContext are
> not ideal because of the name "SQL"/"Hive", and "SparkContext" is not ideal
> because of its heavy dependency on RDDs)
> 3. First class support for sessions
> 4. First class support for some system catalog
> See the design doc for more details.
