             Summary: Consider locking principal/privilege update and Sentry 
refresh operations 
                 Key: IMPALA-7763
                 URL: https://issues.apache.org/jira/browse/IMPALA-7763
             Project: IMPALA
          Issue Type: Improvement
          Components: Catalog
            Reporter: Fredy Wijaya


There's currently no lock between a Sentry refresh and any operations outside 
Sentry refresh for updating principal and privileges, which can cause the 
catalog to be temporarily inconsistent.
