Plugins Support to extend Apache Ambari Functionality

Hi Everyone,

Does Apache Ambari support custom plugin development, by which one can 
extend Ambari functionality ? Are there any custom plugins already out 
there ?

Custom functionality might be following :

  * Install, Monitor, Start, Stop and Restart of Custom Java processes
    (Example : Kafka OR In-House Java Frameworks or tools which run on
    distributed mode)
  * Creating custom UI to monitor the above added Custom Java Processes.

Thanks Jeff and Yusaku. The information was very helpful. I am trying add
support for Kafka in Ambari. Will keep asking questions if am stuck
anywhere.
