This is a example for Spark Compute Plugin that one can make a copy of to get started with building Spark Compute plugin.
Please follow the steps to create a Spark compute plugin
Clone the this repo to your local environment
git clone https://github.com/hydrator/example-sparkcompute.git myplugin-sparkcompute
To build your plugins:
mvn clean package -DskipTests
The build will create a .jar and .json file under the target
directory.
These files can be used to deploy your plugins.
The Cask Hydrator UI displays each plugin property as a simple textbox. To customize how the plugin properties
are displayed in the UI, you can place a configuration file in the widgets
directory.
The file must be named following a convention of [plugin-name]-[plugin-type].json
.
See Plugin Widget Configuration for details on the configuration file.
The UI will also display a reference doc for your plugin if you place a file in the docs
directory
that follows the convention of [plugin-name]-[plugin-type].md
.
When the build runs, it will scan the widgets
and docs
directories in order to build an appropriately
formatted .json file under the target
directory. This file is deployed along with your .jar file to add your
plugins to CDAP.
You can deploy your plugins using the CDAP CLI:
> load artifact <target/plugin.jar> config-file <target/plugin.json>
For example, if your artifact is named 'my-plugins-1.0.0':
> load artifact target/my-plugins-1.0.0.jar config-file target/my-plugins-1.0.0.json
