--------------------------------------

I don't have a good handle on what actually is the problem. [~yhuai] could you 
give us some pointers?


> JVMObjectTracker.objMap may leak JVM objects

>                 Key: SPARK-17822
>                 URL: https://issues.apache.org/jira/browse/SPARK-17822
>             Project: Spark
>          Issue Type: Bug
>          Components: SparkR
>            Reporter: Yin Huai

> Seems it is pretty easy to remove objects from JVMObjectTracker.objMap. So, 
> seems it makes sense to use weak reference (like persistentRdds in 
> SparkContext).
