Capture build scans on ge.apache.org to benefit from deep build insights (#1665) This PR publishes a build scan for every CI build on Jenkins and GitHub Actions and for every local build from an authenticated Apache committer. The build will not fail if publishing fails. The build scans of the Apache Samza project are published to the Gradle Enterprise instance at ge.apache.org, hosted by the Apache Software Foundation and run in partnership between the ASF and Gradle. This Gradle Enterprise instance has all features and extensions enabled and is freely available for use by the Apache Samza project and all other Apache projects. This pull request enhances the functionality of publishing build scans to the publicly available scans.gradle.com by instead publishing build scans to ge.apache.org. On this Gradle Enterprise instance, Apache Samza will have access not only to all of the published build scans but other aggregate data features such as: Dashboards to view all historical build scans, along with performance trends over time Build failure analytics for enhanced investigation and diagnosis of build failures Test failure analytics to better understand trends and causes around slow, failing, and flaky tests If interested in exploring a fully populated Gradle Enterprise instance, please explore the builds already connected to ge.apache.org, the Spring project’s instance, or any number of other OSS projects for which we sponsor instances of Gradle Enterprise.
Apache Samza is a distributed stream processing framework. It uses Apache Kafka for messaging, and Apache Hadoop YARN to provide fault tolerance, processor isolation, security, and resource management.
Samza's key features include:
Check out Hello Samza to try Samza. Read the Background page to learn more about Samza.
To build Samza from a git checkout, run:
./gradlew clean build
To build Samza from a source release, it is first necessary to download the gradle wrapper script above. This bootstrapping process requires Gradle to be installed on the source machine. Gradle is available through most package managers or directly from its website. To bootstrap the wrapper, run:
gradle -b bootstrap.gradle
After the bootstrap script has completed, the regular gradlew instructions below are available.
This project is built with Java 8 and can run in a Java 8 runtime enviornment. Additionally, it also supports running in a Java 11 runtime environment. If you intend to use Samza in a Java 11 runtime environment, it means you will also need to use YARN 3.3.4+ and in which case, you should also use the samza-yarn3
module (built with YARN 3.3.4) instead of the samza-yarn
(built with YARN 2.10.1). There is also a samza-shell-yarn3
that depends on the samza-yarn3
module, so use that shell module if you intend on using Yarn 3.
Samza builds with Scala 2.11 or 2.12 and YARN 2.10.1, by default. Use the -PscalaSuffix switches to change Scala versions. Samza supports building Scala with 2.11 and 2.12 and provides a YARN 2 module (samze-yarn
) and a YARN 3 module (samza-yarn3
).
NOTE: Some modules currently do not officially support Java 11 Runtime and are still using the YARN 2.10.1 dependency:
samza-yarn
samza-shell
samza-test
samza-hdfs
./gradlew -PscalaSuffix=2.12 clean build
Also, you can make use of bin/check-all.sh
in order to test multiple variants of Java JDKs, Scala, and Yarn.
To run all tests:
./gradlew clean test
To run a single test:
./gradlew clean :samza-test:test -Dtest.single=TestStatefulTask
To run key-value performance tests:
./gradlew samza-shell:kvPerformanceTest -PconfigPath=file://$PWD/samza-test/src/main/config/perf/kv-perf.properties
To run yarn integration tests:
./bin/integration-tests.sh <dir> yarn-integration-tests
To run standalone integration tests:
./bin/integration-tests.sh <dir> standalone-integration-tests
./gradlew checkstyleMain checkstyleTest
To run a job (defined in a properties file):
./gradlew samza-shell:runJob -PconfigPath=/path/to/job/config.properties
To inspect a job's latest checkpoint:
./gradlew samza-shell:checkpointTool -PconfigPath=/path/to/job/config.properties
To modify a job's checkpoint (assumes that the job is not currently running), give it a file with the new offset for each partition, in the format systems.<system>.streams.<topic>.partitions.<partition>=<offset>
:
./gradlew samza-shell:checkpointTool -PconfigPath=/path/to/job/config.properties \ -PnewOffsets=file:///path/to/new/offsets.properties
To get Eclipse projects, run:
./gradlew eclipse
For IntelliJ, run:
./gradlew idea
