Merge pull request alteryx#139 from aarondav/shuffle-next
Never store shuffle blocks in BlockManager After the BlockId refactor (PR alteryx#114), it became very clear that ShuffleBlocks are of no use within BlockManager (they had a no-arg constructor!). This patch completely eliminates them, saving us around 100-150 bytes per shuffle block. The total, system-wide overhead per shuffle block is now a flat 8 bytes, excluding state saved by the MapOutputTracker. Note: This should *not* be merged directly into 0.8.0 -- see alteryx#138 (cherry picked from commit 8106532) Signed-off-by: Reynold Xin <[email protected]>
