Customers have CDAP running in AWS, GCE, and Azure.

Do CDAP Pipelines integrate with Apache Sentry for authorization?

CDAP supports integration with Sentry for authorization. Since CDAP pipelines are built using CDAP, the same authorization policies can and are applied as in CDAP.

If I have a question about a data pipeline I am building, how can I get help?

CDAP has an open source support system. It has a Google group where developers and users can ask questions, available at cdapat cdap-users@googlegroupsuser@googlegroups.com. Cask offers commercial CDAP subscriptions, with additional support options.

If I have found an issue with CDAP pipelines, how can I report it?

• Error parsing widgets JSON for the plugin <plugin-name>

  This error means the widget JSON file for the particular plugin has an error in its JSON, such as:

  • You are missing a comma character (,) in the JSON

  • You have a missing a double quote character (") in the JSON

  • You have a value for a key that is not a valid JSON value (for instance, NaN)

  One way to fix these issues is to use json-lint to identify problems and make sure the widget JSON is valid.

• No widgets JSON found for the plugin <plugin-name>

  This error means that the CDAP UI Service could not find the widget JSON for the plugin that you are currently working with. As part of plugin deployment, a JAR and a JSON file are deployed with a plugin, as described in the Packaging Plugins.

In which order do plugin properties appear in the CDAP Studio?
