[Feature Proposal] Spark 2 integration with CarbonData

Hi all,

Currently CarbonData only works with spark1.5 and spark1.6, as Apache Spark
community is moving to 2.1, more and more user will deploy spark 2.x in
production environment. In order to make CarbonData even more popular, I
think now it is good time to start considering spark2.x integration with
CarbonData.

Moreover, we can take this as a chance to refactory CarbonData to make it
both easier to use and higher performance.

Usability:
Instead of using CarbonContext, in spark2 integration, user should able to
1. use native SparkSession in the spark application to create and query
table backed by CarbonData files with full feature support, including index
and late decode optimization.

2. use CarbonData's API and tool to acomplish carbon specific tasks, like
compaction, delete segment, etc.

Perforamnce:
1. deep integration with Datasource API and leveraging spark2's whole stage
codegen feature.

2. provide implementation of vectorized record reader, to improve scanning
performance.

Since spark2 changes a lot comparing to spark 1.6, it may take some time to
complete all these features. With the help of contributors and committers, I
hope we can have basic features working in next CarbonData release.

What do you think about this idea? All kinds of contribution and suggestions
are welcomed.

Regards,
Jacky Li

Hi Ramana,

Sure, I can work out a subtasks list and put it under CARBONDATA-322

Jacky

Hi All,

I agree with Jacky and it is important for CarbonData community to work on
Spark2.x. As Spark2.x has major design and interface changes. It is also
challenge to support both Spark2.x and Spark1.x. We can start creating
sub-tasks under issue(CARBONDATA-322)

Regards,
Ramana

Hi 

Very excited to see that CarbonData will integrate with Spark 2.x, look
forward to getting performance improved further and usability enhanced.

Integration with Spark 2.x is a great feature for Carbondata as Spark 2.x is getting the momentum gradually. This is a big effort ahead and let's take into consideration of all the complexity involved due to dramatic API level change， realizing it in phases is a good idea.

Regards.
