Sean Owen resolved SPARK-809.
-----------------------------
Resolution: Won't Fix
I'm assuming this is WontFix at this point.
> Give newly registered apps a set of executors right away

> Key: SPARK-809
> URL: https://issues.apache.org/jira/browse/SPARK-809
> Project: Spark
> Issue Type: New Feature
> Components: Deploy
> Reporter: Matei Zaharia
> Priority: Minor
>
> Right now, newly connected apps in the standalone cluster will not set a good
> defaultParallelism value if they create RDDs right after creating a
> SparkContext, because the executorAdded calls are asynchronous and happen
> after. It would be nice to wait for a few such calls before returning from
> the scheduler initializer.
