[GitHub] [iceberg] cccs-jc opened a new issue #1941: Support for role based access of HadoopCatalog table listing

[GitBox <gi...@apache.org>]

cccs-jc opened a new issue #1941:
URL: https://github.com/apache/iceberg/issues/1941


   We are using the HadoopCatalog. We find this approach much simpler than the Hive based catalog.
   
   Using the HadoopCatalog all information is on disk which means we can also leverage the role based access of the storage for users that access files directly or via iceberg tables.
   
   However the HadoopCatalog listTables method assumes that all folders in a catalog are accessible by the user/client and throws a RuntimeIOException if it's unable to read from a folder.
   
   https://github.com/apache/iceberg/blob/ab6a5e9ebf2f580fb7be21fb00f1f543726f43eb/core/src/main/java/org/apache/iceberg/hadoop/HadoopCatalog.java#L143
   
   This prevents us from leveraging the storage access controls with the iceberg HadoopCatalog.
   
   Looking at the code it would be easy enough to support a filtered view of the catalog based on access controls.
   
   For backward compatibility there could be a flag that would let you configure the HadoopCatalog to either filter inaccessible folders or throw an exception like it does currently.
   
   Are there any plans to support this feature?
