Change subject: IMPALA-12992: Support for Hive JDBC Storage handler tables ...................................................................... IMPALA-12992: Support for Hive JDBC Storage handler tables This is an enhancement request to support JDBC tables created by Hive JDBC Storage handler. This is essentially done by making JDBC table properties compatible with Impala. It is done by translating when loading the table, and maintaining that only in the Impala cluster, i.e. it's not written back to HMS. Impala includes JDBC drivers for PostgreSQL and MySQL making 'driver.url' not mandatory in such cases. The Impala JDBC driver is still required for Impala-to-Impala JDBC connections. Additionally, Hive allows adding database driver JARs at runtime via Beeline, enabling users to dynamically include JDBC driver JARs. However, Impala does not support adding database driver JARs at runtime, making the driver.url field still useful in cases where additional drivers are needed. 'hive.sql.query' property is not handled in this patch. It'll be covered in a separate jira. Testing: End-to-end tests are included in test_ext_data_sources.py.
