> When executing long linage rdd transform, it is easy to get stack overflow 
> exception in driver end. This can be reproduced by the following example:
> var rdd = sc.makeRDD(1 to 10, 10)
> for (_ <- 1 to 1000) {
>   rdd = rdd.map(x => x)
> }
> rdd.reduce(_ + _)
> SPARK-5955 solve this problem by checkpointing rdd for every 10~20 rounds. It 
> is not so convenient since it required checkpointing data to HDFS. 
> Another solution is cutting off the recursive rdd dependencies in driver end 
> and re-assembly them in executor end.
