Anand Mazumdar commented on MESOS-6127:

I tried to work on trying to add HTTP2 support partially at this years MesosCon 
NA hackathon.

You would still need a library that can understand/parse HTTP2 e.g., libnghttp2 
etc. as you had pointed out earlier. The one which we would eventually choose 
should be ideally be weighted upon in the design doc. Currently, Mesos uses the 
[http-parser|https://github.com/nodejs/http-parser] library which does not 
understand HTTP2 the last time I had a look at it.

I would be happy to shepherd the work for putting the design document in place 
for sharing it with the community.

>             Project: Mesos
>          Issue Type: Epic
>          Components: HTTP API, libprocess
>            Reporter: Aaron Wood
>              Labels: performance
> HTTP/2 will allow us to take advantage of connection multiplexing, header 
> compression, streams, server push, etc. Add support for communication over 
> HTTP/2 between masters and agents, framework endpoints, etc.
> Should we support HTTP/2 without TLS? The spec allows for this but most major 
> browser vendors, libraries, and implementations aren't supporting it unless 
> TLS is used. If we do require TLS, what can be done to reduce the performance 
> hit of the TLS handshake? Might need to change more code to make sure that we 
> are taking advantage of connection sharing so that we can (ideally) only ever 
> have a one-time TLS handshake per shared connection.
