Description	Identifies Join stages where the join key does not match the partitioning key

Description

Parallel Join stages require that their input data are partitioned using the same key(s) as those being used for the Join condition.

If this is not the case then data rows which fulfil the Join condition may not be joined as they will be propagated along different partitions.

Actions

Ensure the Join key and partition keys are aligned.
