> Currently, the BoundedBlockingSubpartition relies on the add of the next 
> BufferConsumer to flush and recycle the previous one, which means we need at 
> least (numsubpartition + 1) buffers to make the bounded blocking 
> ResultPartition work. However, the ResultPartitionFactory gives only 
> (numsubpartition) required buffers to the BoundedBlockingSubpartition which 
> may lead to deadlock.
> This problem exists only in version 1.9. In version 1.10 (master), this 
> problem has been fixed by this commit: 
> 2c8b4ef572f05bf4740b7e204af1e5e709cd945c.
