IMPALA-14746: Calcite planner: Allow overrides in test framework This commit will allow overrides in the test framework for Calcite where the result set is different from the original planner. The overrides will be used if the USE_CALCITE_PLANNER environment variable is set. The allowable overridden sections are: RESULTS, CATCH, RUNTIME_PROFILE. The sections will be overridden if the environment variable is set and if the section has a CALCITE_PLANNER_ prefix (e.g. CALCITE_PLANNER_RESULTS) A sample is given in the subquery.test file.

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.

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.
