Sahil Takiar commented on IMPALA-8391:
--------------------------------------
Found another place the docs need to be updated:
[http://impala.apache.org/docs/build/html/topics/impala_alter_table.html#alter_table]
{quote}
The RENAME TO clause for a Kudu table only affects the name stored in the
metastore database that Impala uses to refer to the table. To change which
underlying Kudu table is associated with an Impala table name, you must change
the TBLPROPERTIES property of the table: SET
TBLPROPERTIES('kudu.table_name'='kudu_tbl_name). You can only change underlying
Kudu tables for the external tables.

> The Impala-Kudu docs:
> [http://impala.apache.org/docs/build/html/topics/impala_kudu.html]
> [http://impala.apache.org/docs/build/html/topics/impala_tables.html]
> Need to be updated after IMPALA-7640 is merged.
> Specifically this part of the docs will no longer be accurate:
> {quote}
> When you create a Kudu table through Impala, it is assigned an internal Kudu
> table name of the form {{impala::db_name.table_name}}. You can see the
> Kudu-assigned name in the output of {{DESCRIBE FORMATTED}}, in the
> {{kudu.table_name}} field of the table properties. The Kudu-assigned name
> remains the same even if you use {{ALTER TABLE}} to rename the Impala table
> or move it to a different Impala database. You can issue the statement{{ALTER
> TABLE impala_name SET TBLPROPERTIES('kudu.table_name' =
> 'different_kudu_table_name')}} for the external tables created with the
> {{CREATE EXTERNAL TABLE}} statement. Changing the {{kudu.table_name}}property
> of an external table switches which underlying Kudu table the Impala table
> refers to. The underlying Kudu table must already exist.
