Add following testcase in LogicalPlanBuilder.java
public void testLogicalPlanCloner() throws CloneNotSupportedException{
LogicalPlan lp = buildPlan("C = join ( load 'A') by $0, (load 'B') by

LogicalPlanCloner cloner = new LogicalPlanCloner(lp);
cloner.getClonedPlan();
}
and this fails with the following stacktrace:
