Jonathan Eagles created TEZ-3334: ------------------------------------ Summary: Tez Custom Shuffle Handler Key: TEZ-3334 URL: https://issues.apache.org/jira/browse/TEZ-3334 Project: Apache Tez Issue Type: Bug Reporter: Jonathan Eagles
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 (v6.3.4#6332)
