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.
