> Currently Embeded jetty Server used across all hadoop services is configured through
ssl-server.xml file from their respective configuration section. However, the SSL/TLS protocol
being used for this jetty servers can be downgraded to weak cipher suites. This code changes
aims to add following functionality:
> 1) Add logic in hadoop common (HttpServer2.java and associated interfaces) to spawn jetty
servers with ability to exclude weak cipher suites. I propose we make this though ssl-server.xml
and hence each service can choose to disable specific ciphers.
> 2) Modify DFSUtil.java used by HDFS code to supply new parameter ssl.server.exclude.cipher.list
for hadoop-common code, so it can exclude the ciphers supplied through this key.
