Forecasting Models with Spark

[#1]

There are some libraries present in python such as statsmodels which have ARIMA, ARMA etc implementation.I was wondering as to how SPARK utilizes them in efficient ways or are there any scala libraries or apache projects already have these models with them?

Have a look at https://github.com/sryza/spark-timeseries for time series on Spark.
