Hi, Now I'm working on dropping Scala 2.10 and Spark 1.6 support at PIO-171.
While I think this work will be targeted to PredictionIO 0.14.0 and I wonder if we can drop further Elasticsearch 1.x support in this version. Elasticsearch 1.x is too old. Of course it's supported by Elastic no longer. If there are no objections, I would like to start to work for this after PIO-171 is merged. -- Naoki Takezoe
