>             Project: Hive
>          Issue Type: Improvement
>          Components: CLI
>    Affects Versions: 2.0.0
>            Reporter: Eric Lin
>            Assignee: Adam Szita
>            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.
