             Summary: Hive Metastore Translation: Bucketed table Readonly 
capability
                 Key: HIVE-21840
                 URL: https://issues.apache.org/jira/browse/HIVE-21840
             Project: Hive
          Issue Type: New Feature
            Reporter: Yongzhi Chen
            Assignee: Naveen Gangam


Impala needs a new capability to tell only read supported for bucketed tables. 
No matter it is managed or external, ACID or not. Also in the current 
implementation, when HIVEBUCKET2 is not in the capabilities list, a bucked 
external table returned as an un-bucketed one,  we need a way to know it is 
"downgraded" from a bucketed table.
