[jira] [Created] (IMPALA-9824) MetastoreClientPool should be singleton

Vihang Karajgaonkar created IMPALA-9824:
-------------------------------------------

             Summary: MetastoreClientPool should be singleton
                 Key: IMPALA-9824
                 URL: https://issues.apache.org/jira/browse/IMPALA-9824
             Project: IMPALA
          Issue Type: Improvement
          Components: Catalog
            Reporter: Vihang Karajgaonkar
            Assignee: Vihang Karajgaonkar


Currently,  the MetastoreClientPool is instantiated at multiple places in the code and it would be good to refactor the code to make it a singleton. Each MetastoreClientPool creates multiple clients to HMS and unnecessary creation of multiple pools could cause problems on HMS side.
