-----------------------------------
Summary: Impala Doc: Clear up Impala' invalidate metadata page
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
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.
