Xiaobing Zhou commented on HIVE-8115:
-------------------------------------
LazyMap was commented as "LazyMap does not deal with the case of a NULL map.
That is handled by the parent LazyObject.", so it'd better to output some
warning message regarding empty key or pair in line 173 of LazyMap.parse().
> Hive select query hang when fields contain map
