> Tez Custom Shuffle Handler

> Key: TEZ-3334
> URL: https://issues.apache.org/jira/browse/TEZ-3334
> Project: Apache Tez
> Issue Type: New Feature
> Reporter: Jonathan Eagles
> Attachments: TEZ-3334.1.patch, TEZ-3334.2.patch, TEZ-3334.3.patch
>
>
> For conditions where auto-parallelism is reduced (e.g. TEZ-3222), a custom
> shuffle handler could help reduce the number of fetches and could more
> efficiently fetch data. In particular if a reducer is fetching 100 pieces
> serially from the same mapper it could do this in one fetch call.
