stack commented on HDFS-7966: ----------------------------- bq. Hopefully we can get things committed soon and continue to make progress. Do you think this should go into a branch first [~wheat9]? It is shaping up as a nice set of sizeable, related patches. 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 > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
