> Really simple request, to upgrade fastutil to 6.5.x.
> The current version, 6.4.x, has some minor API's in the Object2xxOpenHashMap 
> structures which is used in many places in Spark, and has been marked 
> deprecated.
> Plus there is a conflict with another library we are using (saddle -- 
> http://saddle.github.io/) which uses a newer version of fastutil.
> I'd be happy to send a PR.
> I guess a bigger question is do you want to keep using fastutil (SPARK-681) 
> but Spark uses more than just hashmaps, so that probably requires another 
> discussion.
