Subject Re: [jira] [Commented] (REEF-1791) Implement reef-runtime-spark
Date Mon, 08 May 2017 23:23:46 GMT
Markus/Sergiy,
That's what I was trying to convey from the diagram, the scenario is that I
have some job that I'd like to run on a set of spark executors (one can
imagine a distributed machine learning algorithm), however each of these
spark executors needs to execute on a cluster with a set of head and worker
nodes , namely a spark cluster that runs locally in the dev environment ,
in an integration environment the spark cluster will run in distributed
mode on yarn or mesos.

Clear?
