File fe/src/main/java/org/apache/impala/analysis/UnionStmt.java:

Line 371:     for (UnionOperand op: distinctOperands_) {
single line


Line 374:     for (UnionOperand op: allOperands_) {
same


Line 611:    * Undoes all changes made by analyze() except distinct propagation 
and unnesting.
i'm fine with leaving this here, but i think this reflects the ambiguous 
semantics of reset() (what's done here is clearly less than what's asked for in 
StatementBase; the question then is: what are the actual semantics that are 
needed?). just something to keep in mind.
