-----------------------------------------
The API... aka the UDF
> Avoid sending the VertexSpec along with each fragment in GenericUDTFGetSplits
> -----------------------------------------------------------------------------
>
> Key: HIVE-13915
> URL: https://issues.apache.org/jira/browse/HIVE-13915
> Project: Hive
> Issue Type: Improvement
> Reporter: Siddharth Seth
>
> After changes in HIVE-13675, TaskSpec no longer needs to be constructed per
> split, and VertexSpec does not need to be sent over the wire for each split.
> Considering that TaskSpec and VertexSpec can be fairly large - we should
> avoid sending them.
