Subject Re: callJMethod?
Date Thu, 09 Jul 2015 23:41:11 GMT
callJMethod is a private R function that is defined in
https://github.com/apache/spark/blob/a0cc3e5aa3fcfd0fce6813c520152657d327aaf2/R/pkg/R/backend.R#L31

callJMethod serializes the function names, arguments and sends them over a
socket to the JVM. This is the socket-based R to JVM bridge described in
the Spark Summit talk
https://spark-summit.org/2015/events/sparkr-the-past-the-present-and-the-future/

Thanks
Shivaram
