Apache Bigtop is a project focused on building and packaging the Hadoop ecosystem and related big data components. It provides a consistent framework for testing, packaging, and deploying Hadoop distributions, including tools like HDFS, YARN, Spark, Hive, HBase, and more. By maintaining cross-platform builds (RPMs, DEBs, Docker images, and Kubernetes support), Bigtop makes it easier for organizations to deploy big data stacks in different environments. It also includes a set of integration tests and smoke tests to ensure compatibility and stability between ecosystem components. Developers and operators can use Bigtop to assemble customized Hadoop distributions tailored to their infrastructure and workloads. Its focus on reproducibility and packaging reduces friction in deploying large-scale data processing systems and ensures that different components of the Hadoop ecosystem work well together.

AppJoint is a minimalist Android componentization tool that aims to simplify cross-module communication in modularized Android projects. In complex apps broken into multiple modules or “features,” invoking methods or classes across module boundaries can become cumbersome or tightly coupled. AppJoint uses a small set of annotations and a simple runtime API to decouple modules: one module can declare a method interface, annotate it, and other modules can call it dynamically without direct dependency on the implementation. The tool hides much of the boilerplate of dependency injection or manual wiring of interfaces. It allows progressive modularization: you can incrementally introduce AppJoint in parts of an existing app without rewriting everything. The design focuses on being lightweight and easy to adopt—only a few annotations and calls are needed. In multi-module Android architectures, it helps maintain loose coupling and cleaner module boundaries.
