             Summary: Handle CREATE_TABLE event when the db is invisible to the impala server user
                 Key: IMPALA-11735
                 URL: https://issues.apache.org/jira/browse/IMPALA-11735
             Project: IMPALA
          Issue Type: Bug
            Reporter: Quanlong Huang


It's possible that some dbs are invisible to Impala cluster due to authorization restrictions. However, the CREATE_TABLE events in such dbs will lead the event-processor into ERROR state:

It should be handled (e.g. ignored) and reported to the admin (e.g. in logs).
