Actually there are libs that will read DFs from HBase https://svn.apache.org/repos/asf/hbase/hbase.apache.org/trunk/_chapters/spark.html <https://svn.apache.org/repos/asf/hbase/hbase.apache.org/trunk/_chapters/spark.html>
This is out of band with PIO and should not be used IMO because the schema of the EventStore is not guaranteed to remain as-is. The safest way is to translate or get DFs integrated to PIO. I think there is an existing Jira that request Spark ML support, which assumes DFs. On Jan 4, 2018, at 12:25 PM, Pat Ferrel <p...@occamsmachete.com> wrote: Funny you should ask this. Yes, we are working on a DF based Universal Recommender but you have to convert the RDD into a DF since PIO does not read out data in the form of a DF (yet). This is a fairly simple step of maybe one line of code but would be better supported in PIO itself. The issue is that the EventStore uses libs that may not read out DFs, but RDDs. This is certainly the case with Elasticsearch, which provides an RDD lib. I haven’t seen one from them that read out DFs though it would make a lot of sense for ES especially. So TLDR; yes, just convert the RDD into a DF for now. Also please add a feature request as a PIO Jira ticket to look into this.

Does anyone have a working example or template using the DataFrame API vs. the RDD based APIs. We are wanting to migrate to using the new DataFrame APIs to take advantage of the Feature Importance function for our Regression Random Forest Models. We are wanting to move from import org.apache.spark.mllib.tree.RandomForest import org.apache.spark.mllib.tree.model.RandomForestModel import org.apache.spark.mllib.util.MLUtils to import org.apache.spark.ml.regression.{RandomForestRegressionModel, RandomForestRegressor} Is this something that should be fairly straightforward by adjusting parameters and calling new classes within DASE or is it much more involved development.
