>             Project: Spark
>          Issue Type: Improvement
>          Components: Block Manager, Shuffle
>    Affects Versions: 1.6.0

> Currently during spilling of a collection of record, sorter calls {{createTempShuffleBlock}} for allocating a local block. 
> This call provides no size information about required block. Without knowledge of estimated size, this makes customized allocation strategy hard to implement .
> On the other hand, theoretically both {{PartitionedPairBuffer}} and {{PartitionedAppendOnlyMap}} are able to track its estimated size. 
> In this case, it is convenient to extract size information and pass it as parameter to {{createTempShuffleBlock}}.
