Hive 3 changed the typical storage model for tables to split them between two directories: - hive.metastore.warehouse.dir stores managed tables (which is now defined to be only transactional tables) - hive.metastore.warehouse.external.dir stores external tables (everything that is not a transactional table) In more recent commits of Hive, there is now validation that the external tables cannot be stored in the managed directory. In order to adopt these newer versions of Hive, we need to use separate directories for external vs managed warehouses. Most of our test tables are not transactional, so they would reside in the external directory. To keep the test changes small, this uses /test-warehouse for the external directory and /test-warehouse/managed for the managed directory. Having the managed directory be a subdirectory of /test-warehouse means that the data snapshot code should not need to change. The Hive 2 configuration doesn't change as it does not have this concept. Since this changes the dataload layout, this also sets the CDH_MAJOR_VERSION to 7 for USE_CDP_HIVE=true. This means that dataload will uses a separate location for data as compared to USE_CDP_HIVE=false. That should reduce conflicts between the two configurations. Testing: - Ran exhaustive tests with USE_CDP_HIVE=false - Ran exhaustive tests with USE_CDP_HIVE=true (with current Hive version) - Verified that dataload succeeds and tests are able to run with a newer Hive version.
