Hub

The Hub allows CDAP users to create and update CDAP artifacts, applications, and datasets using simple wizards. Instead of building code, deploying artifacts, and configuring applications, users can simply point and click to install any plugin in the Hub.

The Hub allows system administrators to distribute reusable applications, data, and code to all CDAP users in their organization. Though there is currently no method for publishing packages to the public CDAP-hosted Hub, administrators can host their own Hub, and then configure their CDAP instances to use their own Hub instead of the public Hub.

Installing from the Hub

Anything installed from Hub gets installed in the user space while plugins packaged with the product will get installed in system space. For example, installing Google Cloud plugins from Hub will install that version in user space, only in the particular namespace that you're in.
