>                 Key: AMBARI-14231
>                 URL:
>             Project: Ambari
>          Issue Type: Task
>          Components: ambari-server
>    Affects Versions: 2.3.0
>            Reporter: Nisarg Gandhi
>             Fix For: 2.3.0
>         Attachments: AMBARI-14231.1.patch
> Benefits of upgrading to Jetty 9:
> 1. Inherent support for WebSocket
> 2. Jetty 9 implements multi protocol, TLS, push and multiplexing features of SPDY protocol
in an efficient way. SPDY is an improvement in the network transport layer, it can greatly
improve page load times without making any changes at all to a web application.
