    Description

      The usage notes section on this page has information that is from pre-catalog service days:

      A metadata update for an impalad instance is required if:
      
      A metadata change occurs
      and the change is made from another impalad instance in your cluster, or through Hive.
      and the change is made to a metastore database to which clients such as the Impala shell or ODBC directly connect.
      A metadata update for an Impala node is not required when you issue queries from the same Impala node where you ran ALTER TABLE, INSERT, or other table-modifying statement.
      

      This should be cleared up.
      The first point is incorrect, catalogd distributes metadata from other impalads.
      The last point is unnecessary and should be removed.
