IMPALA-10170: Data race on Webserver::UrlHandler::is_on_nav_bar_ This data race can be reproduced by TestCompactCatalogUpdates.test_restart_catalogd, although it does not seem to always occur. The data race was originally reported in a Jenkins job, but I could not reproduce it locally. The fix is to acquire a read lock while reading some UrlHandler objects. I cleaned up some of the other involved variables and made them const. These variables are set during construction time, and never modified afterwards. Testing: * Ran be and custom cluster TSAN tests Change-Id: I6923af4754e3fe72b8b04c5303a1e7a79da7613a Reviewed-on: http://gerrit.cloudera.org:8080/16459 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:
To learn more about Impala as a business user, or to try Impala live or in a VM, please visit the Impala homepage. Detailed documentation for administrators and users is available at Apache Impala documentation.
If you are interested in contributing to Impala as a developer, or learning more about Impala's internals and architecture, visit the Impala wiki.
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.
See Impala's developer documentation to get started.
Detailed build notes has some detailed information on the project layout and build.
