IMPALA-10369: Dump server stacktraces when test_concurrent_ddls.py timeout Recently, we see many timeout failures of test_concurrent_ddls.py in S3 builds, e.g. IMPALA-10280, IMPALA-10301, IMPALA-10363. It'd be helpful to dump the server stacktraces so we can understand why some RPCs are slow/stuck. This patch extracts the logic of dumping stacktraces in script-timeout-check.sh to a separate script, dump-stacktraces.sh. The script also dumps jstacks of HMS and NameNode. Dumping all these stacktraces is time-consuming so we do them in parallel, which also helps to get consistent snapshots of all servers. When any tests in test_concurrent_ddls.py timeout, we use dump-stacktraces.sh to dump the stacktraces before exit. Previously, some tests depend on pytest.mark.timeout for detecting timeouts. It's hard to add a customized callback for dumping server stacktraces. So this patch refactors test_concurrent_ddls.py to only use timeout of multiprocessing. Tests: - Tested the scripts locally. - Verified the error handling of timeout logics in Jenkins jobs Change-Id: I514cf2d0ff842805c0abf7211f2a395151174173 Reviewed-on: http://gerrit.cloudera.org:8080/16800 Reviewed-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com> Tested-by: Impala Public Jenkins <impala-public-jenkins@cloudera.com>
Lightning-fast, distributed SQL queries for petabytes of data stored in Apache Hadoop clusters.
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:

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.
This distribution uses cryptographic software and may be subject to export controls. Please refer to EXPORT_CONTROL.md for more information.
