>             Project: Spark
>          Issue Type: Umbrella
>          Components: ML, MLlib
>            Reporter: Joseph K. Bradley
>            Priority: Minor
>
> Multiple places in MLlib, we broadcast a model before prediction.  Since prediction may be called many times, we should store the broadcast variable in a private var so that we broadcast at most once.
> I'll link subtasks for each problem case I find.
