> Add require for one-based indices in loadLibSVMFile
> Customers frequently use zero-based indices in their LIBSVM files. No
> warnings or errors from Spark will be reported during their computation
> afterwards, and usually it will lead to wired result for many algorithms
> (like GBDT).
> add a quick check.
