John Zhuge updated HADOOP-13597:
--------------------------------
    Attachment: HADOOP-13597.002.patch

Patch 002
- Add “hadoop kms” sub-command. kms.sh is now just a wrapper.
- Read SSL configuration from ssl-server.xml
- Put common SSL config keys in SSLConfig
- Put common HTTP config keys in HttpConfig
- Support all deprecated environment variables and give warning of deprecation
- Enhanced web page /static/index.html, not /index.html due to HttpServer2 
limitation

TESTING DONE
- Run “hadoop key list/create/delete/roll” in non-secure and SSL setup
- All KMS unit tests that actually exercise the full-blown KMS
- Script: hadoop kms, hadoop —daemon start|status|stop kms
- Script: kms.sh run|start|status|stop
- /kms/jmx, /kms/logLevel, /kms/conf, /kms/stack, /logs, and /static

TODO
- Integration testing
- Update docs: index.md.vm

TODO in new JIRAs:
- Full SSL server configuration: 
includeProtocols/excludeProtocols/includeCipherSuites/excludeCipherSuites, etc.
- Share web apps code in Common, HDFS, and YARN

> 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.
