> -----------------------------------------------------
>
> Key: IMPALA-6987
> URL: https://issues.apache.org/jira/browse/IMPALA-6987
> Project: IMPALA
> Issue Type: Bug
> Components: Docs
> Affects Versions: Impala 2.12.0
> Reporter: Alex Rodoni
> Assignee: Alex Rodoni
> Priority: Major
> Fix For: Impala 2.13.0, Impala 3.1.0
>
>
> The usage notes section on this page has information that is from pre-catalog service days:
> {code:java}
> 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.
> {code}
> 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.
