Can you explain your design a bit more.
Do you have any node constraints?
Hash partitioning method does not result in equal size partitions.

It is possible (with small probability and depending on your data) that any partitioning algorithm except round robin will have a sufficiently skewed distribution of rows over nodes that a node gets no rows.

Also check that the stage in question is not constrained to executed in a node pool (a subset of nodes).
