Andrew Wang commented on HADOOP-13597:
--------------------------------------

Is this change and the HTTPFS switch incompatible? I'm guessing yes, since it changes the
configuration for users. If so, please set the "Incompatible" flags for tracking.

> The Tomcat 6 we are using will reach EOL at the end of 2017. While there are other good
options, I would propose switching to {{Jetty 9}} for the following reasons:
> * Easier migration. Both Tomcat and Jetty are based on {{Servlet Containers}}, so we
don't have change client code that much. It would require more work to switch to {{JAX-RS}}.
> * Well established.
> * Good performance and scalability.
> Other alternatives:
> * Jersey + Grizzly
> * Tomcat 8
> Your opinions will be greatly appreciated.
