> 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)..
