[jira] [Created] (IGNITE-4458) Hadoop: striped shuffle mode must be enabled by default

Vladimir Ozerov created IGNITE-4458:
---------------------------------------

             Summary: Hadoop: striped shuffle mode must be enabled by default
                 Key: IGNITE-4458
                 URL: https://issues.apache.org/jira/browse/IGNITE-4458
             Project: Ignite
          Issue Type: Task
          Components: hadoop
    Affects Versions: 1.8
            Reporter: Vladimir Ozerov
            Assignee: Taras Ledkov
             Fix For: 2.0


Striped mode is enabled with {{HadoopJobProperty.SHUFFLE_MAPPER_STRIPED_OUTPUT}}. It shows consistently better results comparing to original shuffling mode.

Possible solutions:
1) Make this property enabled by default;
2) Or totally remove previous mode (do not think it is a good idea)..
