File 
asterixdb/asterix-algebra/src/main/java/org/apache/asterix/optimizer/rules/RemoveUnusedOneToOneEquiJoinRule.java:

Line 159:         for (int i = 0; i < joinOp.getInputs().size(); i++) {
Move the unnest-map gathering/check to line 189. 

Add a method isParentOfUnnestMap(...) to just check if an operator is the 
parent of an unnestmap.

Call 
isParentOfUnnestMap(joinOp.getInputs().get(unusedJoinBranchIndex).getValue()) 
to check the condition at line 189.

One more question:
Should the condition be more general than unnest-map?   Any cardinality 
reduction operator should be qualified here?   E.g., SELECT etc.
