>             Project: Kylin
>          Issue Type: Bug
>            Reporter: Ted Yu
>            Priority: Major
>
> Here is related code:
> {code}
>         sortedStatsSet.addAll(statistics.entrySet());
> {code}
> The entrySet() method is allowed to return a view of the underlying Map in which a single Entry object is reused and returned during the iteration.
> When iterating through such a Map, the Entry value is only valid until you advance to the next iteration.
