> In hbase-spark project, HBaseContext provides bulkload methond for loading 
> spark rdd data to hbase easily.But when i using it frequently, the program 
> will throw "cannot create native thread" exception.
> using pstack command in spark driver process , the thread num is increasing 
> using jstack, named "main-SendThread" and "main-EventThread"  thread so many
> It seems like that , connection created before bulkload ,but close method 
> uninvoked at last
