[jira] [Created] (IMPALA-9542) Catalogd Table Metrics web page has stale tables

Quanlong Huang created IMPALA-9542:
--------------------------------------

             Summary: Catalogd Table Metrics web page has stale tables
                 Key: IMPALA-9542
                 URL: https://issues.apache.org/jira/browse/IMPALA-9542
             Project: IMPALA
          Issue Type: Bug
          Components: Frontend
            Reporter: Quanlong Huang
         Attachments: Selection_041.png

We have 4 metrics-tables in /catalog page of the catalgd web-ui:

* Tables with Highest Memory Requirements
* Tables with Highest Number of Metadata Operations
* Tables with Most Number of Files
* Tables with Longest Metadata Loading Time

They could display inexists tables. E.g. after renaming a database by bunch of "ALTER TABLE old_db.table_name RENAME TO new_db.table_name" commands, both of the old tables and new tables are shown in these metrics. A more friendly behavior is only showing the new tables.
