> HIVE-9845 dealt with reducing the size of HCat split-info, to improve job-launch times for Pig/HCat jobs.
> For large Pig queries that scan a large number of Hive partitions, it was found that the Pig {{UDFContext}} stored full-fat HCat {{InputJobInfo}} objects, thus blowing out the Pig Tez AM. Since this information is already stored in the {{HCatSplit}}, the serialization of {{InputJobInfo}} can be spared.
