Mahout on Spark: random forest
Hi All,
We are currently using Weka. I looked the the site and read briefly about experimental nature of Mahout on Spark. I was wondering how mu of Mahout's functionality is available currently? For example, I am interested in using random forest implementation. I wanted to check if I can use that on top of Spark?

H2O have a very high quality random high performance implementation of
random forests.

Sameer,
h2o is making it's open source RandomForests available via MLlib/Spark
API as well.
you can try them here, h2o.ai
Thanks, Sri

I am not sure they have the forests yet. They have what seems to be a
decently performant decision tree tho.

there is no Random Forest impl on Spark in Mahout yet. Ml-lib has a Random
Forests impl why can't u use that instead.

afaik there's no RF in Mahout on Spark. But there's something that may be
pretty close, in Spark's mlib.
