--------------------------------------
Just wanted to mention Madlib implements it as well:

For context Matlib is used in Greenplum as MPP to support Machine Learning scalable algorithms.

> One very important model in space of Survival Modelling is missing from Spark MLLib v1.3.1. It would be good if Cox Proportional Hazards could be available in next release.
