-------------------------------------------
Summary: RDD.isEmpty method should be overriden in IgniteRDD to
use IgniteCache API
Key: IGNITE-2538
URL: https://issues.apache.org/jira/browse/IGNITE-2538
Project: Ignite
Issue Type: Improvement
Components: Ignite RDD
Reporter: Valentin Kulichenko
Currently calling {{IgniteRDD.isEmpty}} ends up in execution of 1024 Spark
jobs, which is not fast. We should override this method and use native
{{IgniteCache}} API there. Other methods should be also revisited.
