Joe McDonnell created IMPALA-14546:
--------------------------------------
Summary: TestPostgresJdbcTables.test_postgres_jdbc_tables fails on
Ozone due to missing prefix
Key: IMPALA-14546
URL: https://issues.apache.org/jira/browse/IMPALA-14546
Project: IMPALA
Issue Type: Bug
Components: Test
Affects Versions: Impala 5.0.0
Reporter: Joe McDonnell
custom_cluster/test_ext_data_sources.py's
TestPostgresJdbcTables.test_postgres_jdbc_tables is consistently failing as it
is unable to get the postgres JDBC driver:
{noformat}
E InternalException: Data source DataSource{name=impalajdbcdatasource,
location=, className=org.apache.impala.extdatasource.jdbc.JdbcDataSource,
apiVersion=V1} returned an error from prepare(): Failed to retrieve total
number of records: Failed to copy JDBC driver from
'/test-warehouse/data-sources/jdbc-drivers/postgresql-jdbc.jar' to local
filesystem.{noformat}
For tests to work properly on Ozone, they need to use WAREHOUSE_LOCATION_PREFIX
or FILESYSTEM_PREFIX when referring to filesystem locations. The code that
loads the Postgres JDBC driver into Ozone uses the prefix, but this test
doesn't. The test needs to be updated to use the prefix.
