Hi I just read an article [1] about Spark, CDH5 and Java 8 but did not get exactly how Spark can run Java 8 on a YARN cluster at runtime. Is Spark using a separate JVM that run on data nodes or is it reusing the YARN JVM runtime somehow, like hadoop1?
CDH5 only supports Java 7 [2] as far as I know?
