Aihua Xu commented on HIVE-13749:
---------------------------------
OK. So it's not the objects of Conf themselves occupy the memory, but the
instances of the conf (too many of them) as I read from above and HIVE-3098?

> Looking a heap dump of 10GB, a large number of Configuration objects(> 66k
> instances) are being retained. These objects along with its retained set is

> days.
