Sahil Takiar created IMPALA-8391: ------------------------------------ Summary: Impala Doc Key: IMPALA-8391 URL: https://issues.apache.org/jira/browse/IMPALA-8391 Project: IMPALA Issue Type: Sub-task Components: Docs Reporter: Sahil Takiar Assignee: Alex Rodoni
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. {quote} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
