>
> The current hashCode implementation produces poor parallelism when dealing
> with single integers or doubles.
> And for partitioned inserts into a 1 bucket table, there is a significant
> hotspot on Reducer #31.
> Removing the magic number 31 and using a more normal hash algorithm would
> help fix these hotspots.
