Description

The change in IMPALA-3930 states that if only one partition is written (because all partitioning columns are constant or the target table is not partitioned), then the "shuffle" hint leads to a plan where all rows are merged at the coordinator where the table sink is executed.

The documentation of the "shuffle" hint does not mention this behavior.
