Hi jian, thanks for your contribution!

File fe/src/main/java/org/apache/impala/planner/SingleNodePlanner.java:

http://gerrit.cloudera.org:8080/#/c/18705/6/fe/src/main/java/org/apache/impala/planner/SingleNodePlanner.java@2117
PS6, Line 2117:     while (conjunctIter.hasNext()) {
since you didn't remove eqJoinConjuncts's element, you can use 'for 
(BinaryPredicate conjunct: eqJoinConjuncts) {...}' to iterate List.

PS6, Line 2123:       SlotRef innerSlotRef = eq.getChild(1).unwrapSlotRef(true);
