Michael Armbrust resolved SPARK-3084.
-------------------------------------
Resolution: Fixed
Fix Version/s: 1.1.0
> Collect broadcasted tables in parallel in joins
> -----------------------------------------------
>
> Key: SPARK-3084
> URL: https://issues.apache.org/jira/browse/SPARK-3084
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Reporter: Matei Zaharia
> Assignee: Matei Zaharia
> Fix For: 1.1.0
>
>
> BroadcastHashJoin has a broadcastFuture variable that tries to collect the
> broadcasted table in a separate thread, but this doesn't help because it's a
> lazy val that only gets initialized when you attempt to build the RDD. Thus
> queries that broadcast multiple tables would collect and broadcast them
> sequentially.
