Before spark 2.3, spark is compiled using scala 2.11 and 2.10 separately. Spark-2.10 module in Ignite exists to accommodate this, it's not used anywhere else in project. Now spark 2.3 decided to remove support for scala 2.10, so we can safely remove spark-2.10 module in Ignite.
It won't affect visor-console-2.10 and scala-2.10 modules because these two modules are Ignite internal modules to support legacy users using scala 2.10. -- Sent from: http://apache-ignite-developers.2346864.n4.nabble.com/
