Resolution: Fixed
Fix Version/s: 1.1.0
Target Version/s: 1.1.0
> Remove 3 second sleep before starting app on YARN
> -------------------------------------------------
>
> Key: SPARK-1707
> URL: https://issues.apache.org/jira/browse/SPARK-1707
> Project: Spark
> Issue Type: Improvement
> Components: YARN
> Reporter: Sandy Ryza
> Assignee: Sandy Ryza
> Fix For: 1.1.0
>
>
> After acquiring allocations from YARN and launching containers, Spark
> currently waits for 3 seconds for executors to connect to the driver. On
> Spark standalone, nothing like this happens.
> I'm wondering whether we can just remove this sleep entirely. Is there a
> reason I'm missing why YARN is different than standalone in this regard? At
> the least we could do something smarter like wait until all executors have
> registered.
