IMPALA-15318: Stop impalads before clearing custom-cluster tmp dirs _impala_cluster_teardown() cleared the tmp dirs (e.g. the --lineage_event_log_dir target) while impalads were still running, so the lineage flush thread aborted the daemon (abort_on_failed_lineage_event=true) -- an ASAN use-after-free in CI. Now stop the impalads first: a hard kill for tmp-dir tests, a graceful shutdown only for workload_mgmt (to flush query-log rows), and skip both when no cluster was expected to start (so no clients are closed).

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 arm64 (as of Impala 4.4). 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. SLES15/16, 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.
