I am using the latest build of elasticsearch-spark. (2.2.0.BUILD-20150818.024341-55) with Scala 2.11. When I process results from EsSpark.esRdd(), I find that empty columns (or fields) are returned as the string "None" instead of as the empty string. This seems like a bug. Or is there some setting to ensure that I get the empty string and not "None".
Thanks,
