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.
