> Currently, the size of combined splits can be configured by the {{pig.maxCombinedSplitSize}} property.
> Although this works fine most of time, it can lead to a undesired situation where a single mapper ends up loading a lot of combined splits. Particularly, this is bad if Pig uploads them from S3.
> So it will be useful if the max number of combined splits can be configured via a property something like {{pig.maxCombinedSplitNum}}.
