The equivalent for spark-submit --num-executors should be
spark.executor.instancesWhen use in
SparkConf?http://spark.apache.org/docs/latest/running-on-yarn.html
Could you try setting that with sparkR.init()?

Subject: number of executors in sparkR.init()
To: <user@spark.apache.org>
Hi,
I'm having trouble working out how to get the number of executors set
when using sparkR.init().
If I start sparkR with
sparkR --master yarn --num-executors 6
then I get 6 executors
However, if start sparkR with
sparkR
followed by
sc <- sparkR.init(master="yarn-client",
sparkEnvir=list(spark.num.executors='6'))
then I only get 2 executors.
Can anyone point me in the direction of what I might doing wrong ?
I need to initialise this was so that rStudio can hook in to SparkR
thanks
