[jira] [Created] (IMPALA-9088) Deal with customized transformer in HMS

Quanlong Huang created IMPALA-9088:
--------------------------------------

             Summary: Deal with customized transformer in HMS
                 Key: IMPALA-9088
                 URL: https://issues.apache.org/jira/browse/IMPALA-9088
             Project: IMPALA
          Issue Type: Improvement
            Reporter: Quanlong Huang


In Hive-3, HIVE-22158 introduces a default transformer to translate non-ACID managed tables into external tables with appropriated table properties. Customized transformer can be specified by 'metastore.metadata.transformer.class' in hive-site.xml.

With the transformer being set, the HMS Table we passed to the HMS RPC is probably not the same as the created HMS Table, which causing issues like IMPALA-9071. After the create table request succeeds, we should always fetch the table again to get the correct result.
