> Hive version:3.1.2
> Hive metastore heap size is 14GB, Memory Leak is happening after 4-5 days, hive meta-store throwing error with OOM.
> If we disable the configuration, the memory leak disappears.
> In the case of, Heap dump size 3.5GB, a large number of filesystem objects(> 9k instances) are being retained. It's occupying most of the heap space. Added snapshot from the eclipse MAT.
