IMPALA-13003: Handle Iceberg AlreadyExistsException When multiple coordinators attempt to create the same table concurrently with "if not exists", we still see AlreadyExistsException: Table was created concurrently: my_iceberg_tbl Iceberg throws its own version of AlreadyExistsException, but we avoid most code paths that would throw it because we first check HMS to see if the table exists before trying to create it. Updates createIcebergTable to handle Iceberg's AlreadyExistsException identically to the HMS AlreadyExistsException. Adds a test using DebugAction to simulate concurrent table creation.

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.
See Impala's developer documentation to get started.
