Jonathan Eagles updated TEZ-3334: --------------------------------- Attachment: TEZ-3334.1.patch > 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 > > > 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. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
