IMPALA-12611: Add support to MAP type Iceberg Metadata table columns This change adds support for querying MAP types from Iceberg Metadata tables. The 'IcebergMetadataScanner.ArrayScanner' java class is renamed to 'CollectionScanner' and extended to be able to handle maps. For arrays the iteration returns the element as before, for maps it returns 'Map.Entry' objects. Note that collections in the FROM clause are still not supported. Testing: - Added E2E tests in iceberg-metadata-tables.test.

Lightning-fast, distributed SQL queries for petabytes of data stored in open data and table formats.
Impala is a modern, massively-distributed, massively-parallel, C++ query engine that lets you analyze, transform and combine data from a variety of data sources:
The fastest way to try out Impala is a quickstart Docker container. You can try out running queries and processing data sets in Impala on a single machine without installing dependencies. It can automatically load test data sets into Apache Kudu and Apache Parquet formats and you can start playing around with Apache Impala SQL within minutes.
To learn more about Impala as a user or administrator, or to try Impala, please visit the Impala homepage. Detailed documentation for administrators and users is available at Apache Impala documentation.

Impala only supports Linux at the moment. Impala supports x86_64 and has experimental support for arm64 (as of Impala 4.0). Impala Requirements contains more detailed information on the minimum CPU requirements.
Impala runs on Linux systems only. The supported distros are
Other systems, e.g. SLES12, may also be supported but are not tested by the community.
This distribution uses cryptographic software and may be subject to export controls. Please refer to EXPORT_CONTROL.md for more information.
