Eric Lin created HIVE-13780:
-------------------------------
Summary: Allow user to update AVRO table schema via command even
if table's definition was defined through schema file
Key: HIVE-13780
URL: https://issues.apache.org/jira/browse/HIVE-13780
Project: Hive
Issue Type: Improvement
Components: CLI
Affects Versions: 2.0.0
Reporter: Eric Lin
Priority: Minor
If a table is defined as below:
{code}
CREATE TABLE test
STORED AS AVRO
TBLPROPERTIES ('avro.schema.url'='/tmp/schema.json');
{code}
if user tries to run command:
{code}
ALTER TABLE test CHANGE COLUMN col1 col1 STRING COMMENT 'test comment';
{code}
The query will return without any warning, but has no affect to the table.
It would be good if we can allow user to ALTER table (add/change column, update
comment etc) even though the schema is defined through schema file.
