----------------------------------------
FYI: I filed https://issues.apache.org/jira/browse/SPARK-44937 as a follow up
to this ticket. I revived [~turp1twin]'s patch and am cleaning it up before
submitting a PR.
> Add SSL/TLS for the Netty based BlockTransferService
> -----------------------------------------------------
>
> Key: SPARK-6373
> URL: https://issues.apache.org/jira/browse/SPARK-6373
> Project: Spark
> Issue Type: New Feature
> Components: Block Manager, Shuffle, Spark Core
> Affects Versions: 1.2.1
> Reporter: Jeffrey Turpin
> Priority: Major
> Labels: bulk-closed
>
> Add the ability to allow for secure communications (SSL/TLS) for the Netty
> based BlockTransferService and the ExternalShuffleClient. This ticket will
> hopefully start the conversation around potential designs... Below is a
> reference to a WIP prototype which implements this functionality
> (prototype)... I have attempted to disrupt as little code as possible and
> tried to follow the current code structure (for the most part) in the areas I
> modified. I also studied how Hadoop achieves encrypted shuffle
> (http://hadoop.apache.org/docs/current/hadoop-mapreduce-client/hadoop-mapreduce-client-core/EncryptedShuffle.html)
