I don't know if anyone has done benchmarking of different JVMs for Spark
specifically, but the widely-held belief seems to be that the Oracle JDK is
slightly more performant.

Elasticsearch makes heavy usage of Lucene, which is a particularly intense
workout for a JVM, and they recommend using the Oracle JVM where possible.

I would like to say that Oracle JDK may be the better choice. A lot of
hadoop distribution vendors use Oracle JDK instead of Open JDK for
enterprise.
