>
> Patch to add classes to provide a checkpointable version of shuffle and
> reduce context. Also, add a classe which makes possible to save a checkpoint
> of a task in HDFS. Those classes are respectively: CheckpointableShuffle,
> CheckpointableReduceContextImpl and TaskCheckpointManager.
> This improvement also helps in the splitting of patch in MAPREDUCE-5269 that
> is too large for being reviewed or accepted by Jenkins CI scripts.
