This PR doesn't include examples, documentation and spark.ml APIs. I am going to send another PRs later.\r\nhttps://issues.apache.org/jira/browse/SPARK-6517\r\n\r\n- This implementation based on a bi-sectiong K-means clustering.\r\n    - It derives from the @freeman-lab 's implementation\r\n- The basic idea is not changed from the previous version. (#2906)\r\n    - However, It is 1000x faster than the previous version through parallel processing.\r\n\r\nThank you for your great cooperation, RJ Nowling(@rnowling), Jeremy Freeman(@freeman-lab), Xiangrui Meng(@mengxr) and Sean Owen(@srowen)."},"comment":{"url":"https://api.github.com/repos/apache/spark/issues/comments/155190941","html_url":"https://github.com/apache/spark/pull/5267#issuecomment-155190941","issue_url":"https://api.github.com/repos/apache/spark/issues/5267","id":155190941,"user":{"login":"AmplabJenkins","id":4031291,"avatar_url":"https://avatars.githubusercontent.com/u/4031291?v=3","gravatar_id":"","url":"https://api.github.com/users/AmplabJenkins","html_url":"https://github.com/AmplabJenkins","followers_url":"https://api.github.com/users/AmplabJenkins/followers","following_url":"https://api.github.com/users/AmplabJenkins/following{/other_user}","gists_url":"https://api.github.com/users/AmplabJenkins/gists{/gist_id}","starred_url":"https://api.github.com/users/AmplabJenkins/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/AmplabJenkins/subscriptions","organizations_url":"https://api.github.com/users/AmplabJenkins/orgs","repos_url":"https://api.github.com/users/AmplabJenkins/repos","events_url":"https://api.github.com/users/AmplabJenkins/events{/privacy}","received_events_url":"https://api.github.com/users/AmplabJenkins/received_events","type":"User","site_admin":false},"created_at":"2015-11-09T20:57:53Z","updated_at":"2015-11-09T20:57:53Z","body":"Merged build finished.
