Thejas M Nair updated HIVE-11407:
---------------------------------
Description:
With around 7000 tables having around 1500 columns each, and 512MB of HS2
memory, I am able to reproduce this OOM .
Most of the memory is consumed by the datanucleus objects.
Reducing the number of tables for which metadata is fetched at a time via
metastore get_multi_table limits the memory footprint.
