Resolution: Won't Fix
> Only use broadcast for large tasks
> ----------------------------------
>
> Key: SPARK-4087
> URL: https://issues.apache.org/jira/browse/SPARK-4087
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Reporter: Davies Liu
> Priority: Critical
>
> After we broadcast every tasks, some regressions are introduced because of
> broadcast is not stable enough.
> So we would like to only use broadcast for large tasks, which will keep the
> same behaviour as 1.0 for most of the cases.
