My guess - you have identically-named columns on both inputs and the result of the join - you have not provided separate output columns into which to map the left and right input columns.

To add to what Ray has already said, another possibility is that you have runtime column propagation turned on and don't directly "see" the duplicated column name becuase it has been passed in from a previous stage.
