Matei Zaharia resolved SPARK-681.
---------------------------------
Resolution: Fixed
> Optimize hashtables used in Spark
> ---------------------------------
>
> Key: SPARK-681
> URL: https://issues.apache.org/jira/browse/SPARK-681
> Project: Spark
> Issue Type: Improvement
> Reporter: Matei Zaharia
>
> The hash tables used in cogroup, join, etc take up a lot more space than they
> need to because they're using linked data structures. It would be nice to
> write a custom open hashtable class to use instead, especially since these
> tables are "append-only". A custom one would likely run better than fastutil
> as well.
