> Reporter: Felix Cheung
> Assignee: Apache Spark
> Priority: Minor
>
> Several Spark properties equivalent to Spark submit command line options are
> missing.
> {quote}
> The equivalent for spark-submit --num-executors should be
> spark.executor.instances
> When 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: <u...@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
