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.
