Commit 7e5bb385e1d391c790c6645e5abc3d38d37f39f0 in impala's branch
refs/heads/master from Peter Rozsa
[ https://gitbox.apache.org/repos/asf?p=impala.git;h=7e5bb385e ]
Addendum: IMPALA-12584: Enable strict data file access by default
This change sets the default value to 'true' for
'iceberg_restrict_data_file_location' and changes the flag name to
'iceberg_allow_datafiles_in_table_location_only'. Tests related to
multiple storage locations in Iceberg tables are moved out to custom
cluster tests. During test data loading, the flag is set to 'false'
to make the creation of 'iceberg_multiple_storage_locations' table
possible.

> Project: IMPALA
> Issue Type: Bug
> Reporter: Zoltán Borók-Nagy
> Assignee: Peter Rozsa
> Priority: Major
> Labels: impala-iceberg
> Fix For: Impala 4.4.0
>
>
> Similarly to [https://github.com/apache/hive/pull/4910,] Impala should have a
> backend flag to restrict the data file locations of Iceberg tables.
> If the flag is true, Impala should raise an error for Iceberg tables that
> have data files outside of the table directory.
> We should not limit the location of metadata files, so they could be placed
> to a different storage system (e.g. Amazon S3 Express).
> We must also ensure that users cannot create Iceberg tables at arbitrary
> locations.
