> Key: IMPALA-10740
> URL: https://issues.apache.org/jira/browse/IMPALA-10740
> Project: IMPALA
> Issue Type: Improvement
> Components: Catalog
> Reporter: Kishen Das
> Assignee: Kishen Das
> Priority: Major
>
> 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
> need a way to redirect the new HMS API to HMS itself, if we do not have to
> implement the same in CatalogD. This new class DefaultThriftHiveMetastore in
> Hive does exactly that. So, MetastoreServiceHandler should now extend
> DefaultThriftHiveMetastore.
