> Key: TEZ-779
> URL: https://issues.apache.org/jira/browse/TEZ-779
> Project: Apache Tez
> Issue Type: Improvement
> Reporter: Siddharth Seth
>
> Grouping currently fetches splits from the underlying file format.
> It'd be useful to allow grouping to accept a set of splits instead of always
> fetching them from the underlying format.
> One example of where this will be used : Bucketed Hive data - regular
> HiveInputFormat splits are generated, only splits belonging to the same
> bucket can be Grouped together.
