- Frontend has been re-implemented as full screen pages.
- Hue supports LDAP (OpenLDAP and Active Directory). Hue can be configured to authenticate against LDAP. Additionally, Hue can import users and groups from LDAP, and refresh group membership from LDAP.
- Hue supports per-application authorization. Administrators can grant or limit group access to applications.
- Hue has a new Shell application, which allows access to the HBase shell, Pig shell, and more.
- The Job Designer now submits jobs through Oozie, which is more secured.
For end users, this means that every page view has its own URL and can be bookmarked. Users also have better control of the windowing behaviours (maximize, minimize, alt-tab) and browsing history. And for enterprise users, Hue 2.0 works on Internet Explorer, which is plagued by memory reclamation issues with Hue 1.x.
Applications written for Hue 1.x are not compatible with Hue 2.0. Fortunately, the transition is straightforward and is documented in the SDK guide. For example, Hue 1.x provides an “HtmlTable” widget that supports banding, column sorting and more. In Hue 2.0, the same functionality is provided by the DataTables.
Hue 2.0.1 is compatible with (and included in) CDH4.
- It works with HA NameNode, since it communicates with HDFS via the HttpFS REST API.
- It can submit jobs to YARN, since job submission is executed via Oozie. But it cannot browse any YARN jobs.
- It supports Hive 0.8.1.
