[jira] [Created] (IMPALA-7762) Add a timeout in Impala when waiting for a catalog update

Fredy Wijaya created IMPALA-7762:
------------------------------------

             Summary: Add a timeout in Impala when waiting for a catalog update
                 Key: IMPALA-7762
                 URL: https://issues.apache.org/jira/browse/IMPALA-7762
             Project: IMPALA
          Issue Type: Bug
          Components: Catalog
            Reporter: Fredy Wijaya


When something goes wrong, "invalidate metadata" can cause a hang while waiting for a catalog update that never arrives. There's a TODO (https://github.com/apache/impala/blob/1d72c7584fd33746b17826c1dc54a1819fce9ec5/be/src/service/impala-server.cc#L1612-L1620) in the code to set a timeout instead of waiting indefinitely.
