Fix Version/s: Impala 3.4.0
Resolution: Fixed
> Impala should respect the distinction between the managed warehouse and the
> external warehouse

> Key: IMPALA-9068
> URL: https://issues.apache.org/jira/browse/IMPALA-9068
> Project: IMPALA
> Issue Type: Bug
> Components: Infrastructure
> Affects Versions: Impala 3.4.0
> Reporter: Joe McDonnell
> Priority: Blocker
> Fix For: Impala 3.4.0
>
>
> Recent Hive 3 makes a distinction between the directory for managed tables
> and the directory for external tables.
> {code:java}
> WAREHOUSE("metastore.warehouse.dir", "hive.metastore.warehouse.dir",
> "/user/hive/warehouse",
> "location of default database for the warehouse"),
> WAREHOUSE_EXTERNAL("metastore.warehouse.external.dir",
> "hive.metastore.warehouse.external.dir", "",
> "Default location for external tables created in the warehouse. " +
> "If not set or null, then the normal warehouse location will be used
> as the default location."),
> {code}
> With HIVE-22189, Hive is militantly enforcing the distinction. It no longer
> allows external tables in the hive.metastore.warehouse.dir (the managed
> directory). The create table statements are currently translated to create
> external table statements with appropriate table properties, but in order for
> this to work correctly, we need to specify
> hive.metastore.warehouse.external.dir to be different from
> hive.metastore.warehouse.dir. A sensible approach is to set
> hive.metastore.warehouse.external.dir to /test-warehouse and change
> hive.metastore.warehouse.dir to something else, like /test-warehouse-managed.
> This will require further changes in our test infrastructure to incorporate
> this distinction. For example, tests/comparison/cluster/cluster.py's
> warehouse_dir needs to handle this appropriately (this is needed for
> testdata/bin/load_nested.py). It may also require changes to some paths for
> tests that use managed tables.
> hive.metastore.warehouse.external.dir does not exist in Hive 2, so this will
> require some Hive 3 specific logic.
