Review Comment:
   Nit: this int parsing can be moved inside the if block as it doesn't need to 
be done unless the `outputLocation` is non-null.

> The Graph export to HDFS through OutputRDD, but we often saw there are many 
> small files in production environment. For example, there are more than 
> 50,000 files and each is about 17 MB, which will trigger HDFS small files 
> alerts. So, it is better allow customize the output file numbers by 
> repartition the OutputRDD.
