------------------------------------
Summary: Support different schemes for jdbc driver url when
creating external jdbc table
Key: IMPALA-12470
URL: https://issues.apache.org/jira/browse/IMPALA-12470
Project: IMPALA
Issue Type: Sub-task
Components: Frontend
Reporter: Wenzhe Zhou
jdbc driver url is specified as table property 'driver.url' when creating a
external jdbc table, like the sample below:
{code:java}
CREATE TABLE test_postgres (
id INT,
string_col STRING)
PRODUCED BY DATA SOURCE JdbcDataSource(
'{"database.type":"POSTGRES",
"jdbc.url":"jdbc:postgresql://localhost:5432/functional",
"jdbc.driver":"org.postgresql.Driver",
"driver.url":"hdfs://localhost:20500/test-warehouse/data-sources/jdbc-driver/postgresql-jdbc.jar",
"dbcp.username":"hiveuser",
"dbcp.password":"password",
"table":"alltypes"}');
{code}
In the initial patch, we only support to download the driver jar files from
hdfs. We need to support different storage type, like 'file://', 's3a://',
etc.
