Will implement read block at this branch and collect some performance results
first.
Thanks.
> 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

>
> 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.
