John Zhuge commented on HADOOP-13597:
-------------------------------------

[~aw] I was about to ping you on the rewrite, thanks for the quick feedback !

It seems more natural to move it into a sub-command of bin/hadoop.

Also ok to move sbin/kms.sh to bin/kms, while I found it a little awkward for 
this kind of script where there is one single implicit subcommand, unlike 
hadoop/hdfs/yarn scripts.

> 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.
