> callback
> -----------------------------------------------------------------------------------

> Key: SPARK-9026
> URL: https://issues.apache.org/jira/browse/SPARK-9026
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Reporter: Josh Rosen
> Assignee: Josh Rosen
> Fix For: 2.0.0
>
>
> As [~zsxwing] points out at
> https://github.com/apache/spark/pull/7276#issuecomment-121097747,
> SimpleFutureAction currently blocks a separate execution context thread for
> each callback registered via onComplete:
> {code}
> override def onComplete[U](func: (Try[T]) => U)(implicit executor:
> ExecutionContext) {
> executor.execute(new Runnable {
> override def run() {
> func(awaitResult())
> }
> })
> }
> {code}
> We should fix this so that callbacks do not steal threads.
