> Key: IGNITE-4097
> URL: https://issues.apache.org/jira/browse/IGNITE-4097
> Project: Ignite
> Issue Type: Sub-task
> Components: hadoop
> Affects Versions: 1.6
> Reporter: Ivan Veselovsky
> Assignee: Vladimir Ozerov
>
> Implement spilled output on Map side of map-reduce.
> In general, algorithm should follow the one used in Hadoop. The difference on
> the Map side is that
> 1) we use sorting collection (Hadoop sorts a range of map outputs explicitly);
> 2) we store the map output in files not using FileSystem , but rather local
> files.
