Louis Ryan commented on HDFS-7966:
----------------------------------
Hey,
Im the one working on the grpc impl for HBase so I can help answer questions on
that.
1 - grpc is a general purpose content type agnostic transport layer so you can
happily use it without using proto.
2 - If you're using your own payload encoding then tagging flush points in a
streaming RPC seems pretty trivial.
If you'd like to try grpc let me know and I can provide pointers / answer
questions
> New Data Transfer Protocol via HTTP/2
> -------------------------------------
>
> Key: HDFS-7966
> URL: https://issues.apache.org/jira/browse/HDFS-7966
> Project: Hadoop HDFS
> Issue Type: New Feature
> Reporter: Haohui Mai
> Assignee: Qianqian Shi
> Labels: gsoc, gsoc2015, mentor
> Attachments: GSoC2015_Proposal.pdf

>
> The current Data Transfer Protocol (DTP) implements a rich set of features
> that span across multiple layers, including:
> * Connection pooling and authentication (session layer)
> * Encryption (presentation layer)
> * Data writing pipeline (application layer)
> All these features are HDFS-specific and defined by implementation. As a
> result it requires non-trivial amount of work to implement HDFS clients and
> servers.
> This jira explores to delegate the responsibilities of the session and
> presentation layers to the HTTP/2 protocol. Particularly, HTTP/2 handles
> connection multiplexing, QoS, authentication and encryption, reducing the
> scope of DTP to the application layer only. By leveraging the existing HTTP/2
> library, it should simplify the implementation of both HDFS clients and
> servers.
