Re: Spark data frames integration merged

Hello, guys. Currently `getPreferredLocations` implemented in `IgniteRDD -> IgniteAbstractRDD`. But DataFrame implementation uses `IgniteSQLDataFrameRDD -> IgniteSqlRDD -> IgniteAbstractRDD` Where `->` is extension. So, for now, getPreferredLocation doesn't implemented for a IgniteDataFrame.

Spark data frames integration merged

Igniters, Great news! We completed and merged first part of integration with Spark data frames [1]. It contains implementation of Spark data source which allows to use DataFrame API to query Ignite data, as well as join it with other data frames originated from different sources. Next planned ste
