[jira] [Created] (IMPALA-10740) MetastoreServiceHandler should extend DefaultThriftHiveMetastore

Kishen Das created IMPALA-10740:
-----------------------------------

             Summary: MetastoreServiceHandler should extend DefaultThriftHiveMetastore
                 Key: IMPALA-10740
                 URL: https://issues.apache.org/jira/browse/IMPALA-10740
             Project: IMPALA
          Issue Type: Improvement
          Components: Catalog
            Reporter: Kishen Das


Earlier we made MetastoreServiceHandler to extend AbstractThriftHiveMetastore, which had the logic of throwing unsupported operation exception for all HMS APIs. This only solves the build problem we had on Impala, whenever a new HMS API is introduced. However, by default we should need a way to redirect the new HMS API to HMS itself, if we do not have implement the same in CatalogD. This new class DefaultThriftHiveMetastore in Hive does exactly that. So, MetastoreServiceHandler should now extend DefaultThriftHiveMetastore.
