ORC is a supported file format in the HDP platform. That being said individual projects within the platform may not be able to leverage that file format properly. As of HDP 2.3.0, which includes Spark 1.3.1, Spark support for ORC is currently a Tech Preview. However, Spark 1.4 provides native support for reading/writing an ORC file to/from an RDD. So you should expect to see Sparks support for ORC to be GA when Spark 1.4.1 is GA in HDP (which as of Sept-2015, it's tentative for the next HDP 2.3 maintenance release) ... View more
