IMPALA-9008: Serialize Maven invocations to deflake query-event-hook-api The previous commit for this Jira serialized the compilation of shaded-deps and ext-data-source to fix flakiness. It looks like this led to a new similar issue related to the parallel compilation of ext-data-source and query-event-hook-api. Similarly to the shaded-deps issue, I try to fix this by adding a fictional dependency (query-event-hook-api -> yarn-extras) to serialize the build. Full Maven dependency graph: fe -> query-event-hook-api -> yarn-extras -> ext-data-source -> shaded-deps-> impala-parent The ordering of query-event-hook-apit, yarn-extras, ext-data-source, and shaded-deps are arbitrary.

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.
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.
This distribution uses cryptographic software and may be subject to export controls. Please refer to EXPORT_CONTROL.md for more information.
See bin/bootstrap_build.sh.
Impala can be built with pre-built components or components downloaded from S3. The components needed to build Impala are Apache Hadoop, Hive, HBase, and Sentry. If you need to manually override the locations or versions of these components, you can do so through the environment variables and scripts listed below.
Location | Purpose |
---|---|
bin/impala-config.sh | This script must be sourced to setup all environment variables properly to allow other scripts to work |
bin/impala-config-local.sh | A script can be created in this location to set local overrides for any environment variables |
bin/impala-config-branch.sh | A version of the above that can be checked into a branch for convenience. |
bin/bootstrap_build.sh | A helper script to bootstrap some of the build requirements. |
bin/bootstrap_development.sh | A helper script to bootstrap a developer environment. Please read it before using. |
