Summary: 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
Data source tables don't support ALTER TABLE since connection credentials are
set as in 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 with ALTER TABLE statement.
