Project Overview + +The `hadoop-release-support` project is a specialized toolset designed to assist in the creation, validation, and release of Apache Hadoop release candidates. It provides a collection of scripts and configurations to automate and streamline the complex process of producing a stable Hadoop release. The project uses Apache Ant for orchestration of the release tasks and Apache Maven for dependency management and running validation tests. + +## 2. Technologies + +* **Java**: The core language for the validation code. +* **Apache Ant**: Used to script and orchestrate the entire release workflow, from building and testing to staging and publishing. +* **Apache Maven**: Used for managing project dependencies, building the Java code, and running tests to validate the classpath and basic functionality. + +## 3. Project Structure + +The project is organized as follows: + +- `src/`: Contains the source code, release information, and text templates. + - `main/java/`: Java source code for compile-time validation of the Hadoop classpath. + - `releases/`: Property files for different Hadoop releases, containing version numbers, commit IDs, and other release-specific information. + - `test/java/`: Java test source code. +- `build.xml`: The main Ant build file that orchestrates the entire release process. It contains a large number of targets for various tasks like building, testing, signing, and publishing release artifacts. +- `pom.xml`: The Maven project file. It defines the project's dependencies on various Hadoop modules and is used to run basic validation tests. +- `release.properties`: A simple properties file that points to the current Hadoop release being worked on. +- `README.md`: Provides a detailed explanation of the project, its prerequisites, and the complete workflow for creating and validating a Hadoop release. + + +The Ant build file also provides targets for more extensive testing, including running tests against downstream projects like Apache Spark and Google Cloud Storage connector. + +The maven project is purely used to validate artifact download and their dependencies. + +## 6. Release Process + +The main purpose of this project is to manage the Hadoop release process. The `build.xml` Ant script is the central component of this process. It defines a comprehensive workflow that includes: + +* Fetching release candidates. +* Verifying GPG signatures. +* Building from source. +* Running tests against binary distributions. +* Building and testing downstream projects. +* Staging artifacts for release. +* Generating release announcements and vote messages. + +The `README.md` file contains a detailed step-by-step guide on how to perform a release using the Ant targets provided in this project. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
