Prediction.io - pio train fails with exception - prediction

Question

just getting started with Prediction.IO - Getting an exception when performing pio train. I'm using the universal recommender template.
Pio status, and pio-start-all working fine, reporting no errors
Seems " nor Elasticsearch client found" - but curl localhost fine on port 9200.
Does anybody has a clue on what the error message given is referring to?

Answer 1

The default configuration for PredictionIO (in pio-env.sh in your PredictionIO /conf directory) has ElasticSearch running on port 9300. If you update it to 9200 there does your training step succeed?
