Thank you for your response. The algorithm that I am proposing is Isolation Forest. Link to paper: paper <https://cs.nju.edu.cn/zhouzh/zhouzh.files/publication/tkdd11.pdf>. I particularly find that it should be included in Spark ML because so many applications that use Spark as part of real time streaming engine in industry need anomaly detection and current Spark ML supports it in some way by means clustering. I will probably start to create the implementation and prepare for proposal as you suggested.
It is interesting to know that Spark is still implementing stuff in Spark ML to reach full parity with MLlib. Can I please get connected to folks working on it as I am interested in contributing. I have been heavy user of Spark since summer'15.
