This patch changes syntax of creating JDBC table statement as
CREATE TABLE [IF NOT EXISTS] [db_name.]table_name
(col_name data_type
[constraint_specification]
[COMMENT 'col_comment']
[, ...]
)
[COMMENT 'table_comment']
STORED BY JDBC
TBLPROPERTIES ('key1'='value1', 'key2'='value2', ...)
Both "STORED BY JDBC" and "STORED AS JDBC" are acceptable. A table
property '__IMPALA_DATA_SOURCE_NAME' is added to the JDBC table with
value 'impalajdbcdatasource', which is shown in the output of command
'show create table'.
Following required JDBC parameters must be specified as table
properties: database.type, jdbc.url, jdbc.driver, driver.url, and table.
Otherwise, AnalysisException will be thrown.
Testing:
- Added frontend unit tests for new syntax of creating JDBC table.
- Updated end-to-end unit tests to create JDBC tables without data
source.
- Passed core tests
