[GitHub] [iceberg] pvary opened a new issue #2474: Hive: Check the increased usage of HMSClients in TestHiveIcebergStorageHandlerWithEngine tests

pvary opened a new issue #2474:
URL: https://github.com/apache/iceberg/issues/2474


   In #2448 we found that the number of the used HMSClients are increased above 5, and we exhaust the Metastore threadpool.
   
   We should check if the increase is valid, or we have a leak somewhere.
   
   I have 2 ideas:
   - Maybe this was caused by the #2129 where we start to handle / cache the catalogs differently
   - Or we added some more queries and Hive creates / caches HMSClients and we might ended up using a different codepath.
