--------------------------------------------
> Support ALTER TABLE for JDBC tables
> -----------------------------------
>
> Key: IMPALA-12802
> URL: https://issues.apache.org/jira/browse/IMPALA-12802
> Project: IMPALA
> Issue Type: Sub-task
> Components: Frontend
> Reporter: Wenzhe Zhou
> Assignee: Wenzhe Zhou
> Priority: Major
>
> Currently ALTER TABLE is not supported for data source tables since
> connection credentials are set as in single initString. See
> https://github.com/apache/impala/blob/master/fe/src/main/java/org/apache/impala/analysis/AlterTableStmt.java#L103-L108.
> IMPALA-12793 change the syntax for creating JDBC table. The configuration of
> connection credentials - url, username, password, jdbc driver, etc, are set
> as table properties. We should allow user to change these properties or edit
> a column name via ALTER TABLE statement.
