JarCastingHydrator Plugins Collection
Introduction
The Cask™ Data Application Platform (CDAP) is an integrated, open source application development platform for the Hadoop ecosystem that provides developers with data and application abstractions to simplify and accelerate application development.
Cask Hydrator is one such application built by the team at Cask for solving data ingestion problems. It's a CDAP native application that runs at scale on Hadoop. Hydrator exposes APIs that allows one to build, extend, and integrate with Hadoop native and non-Hadoop systems.
This repository is a collection of Hydrator plugins that were built by the team at Cask and by people in the CDAP community. If you are interested in building and contributing a plugin, you are more than welcome to do so. If you would like to build plugins, here are links to get you started:
- Overview of Hydrator
- How to build custom Hydrator plugins
- How to test a plugin
- How to package a plugin
- How to deploy a plugin
- How to include (deploy) third-party JARs

Getting Started
Prerequisites
To use the 1.4.x version of Hydrator plugins, you must have CDAP version 3.5.x or higher. Prerequisites for the various sources, sinks, and transforms are included in their individual README files.
Building Plugins
You get started with Hydrator plugins by building directly from the latest source code:
git clone https://github.com/caskdata/hydrator-plugins.git cd hydrator-plugins git submodule update --init --recursive --remote mvn clean package
After the build completes, you will have a JAR for each plugin under each <plugin-name>/target/ directory.
Deploying Plugins
You can deploy a plugin using the CDAP CLI:
> load artifact <target/plugin-jar> config-file <resources/plugin-config>
Example for loading the Cassandra Plugin (from the cassandra-plugins directory):
> load artifact target/cassandra-plugins-<version>.jar \
config-file target/cassandra-plugins-<version>.json
You can build without running tests: mvn clean install -DskipTests
