<https://reviews.apache.org/r/27745/#comment101753>

    What if there are 2 partitions for big table?  I guess they will then be processed on
2 separate spark nodes, right?  
    
    So in this case, there are 2 replicas created for this HashTableSink. How do we control
that these 2 replicas will be on the same data nodes as the ones where the 2 big table partitions
will be processing map-joins ?
