> Project: Ignite
> Issue Type: Task
> Components: hadoop

> Reporter: Vladimir Ozerov

> 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)..
