It seems that JavaSparkContext is just a wrapper of scala sparkContext.
In JavaSparkContext, the scala one is used to do all the job.
If I pass the same scala sparkContext to initialize JavaSparkContext, I
still manipulate on the same sparkContext.
Sry for spamming.

What problem will multiple sparkContext cause ？
