Hue v1.1.0, released Oct 11, 2010

Hue is a web interface for Hadoop, and a platform for building custom applications with a rich framework. The 1.1.0 is a minor release, largely focused on adding security support to Hue, matching the security support of Cloudera’s Distribution for Hadoop 3, beta 3.

1. Notable Changes and Caveats

Kerberos Integration for Secured Hadoop Clusters:

  • Authenticated access to Hadoop File System
  • Authenticated job submission

Frontend and SDK:

  • Support for tree-view table, in which a row can be expanded to show its children rows.
  • Improvement to double-click handling.
  • Improvement to meta-refresh handling.
  • JFrame Filter to load content into a DIV via AJAX.
  • JFrame Filter to update the active url in a JBrowser.

Documentation:

  • Fixes to Help application to improve reliability.
  • Updates to Beeswax, File Browser, Job Designer.

Caveats:

  • Hue 1.1.0 only works with CDH3b3 or newer. CDH2 and earlier versions of CDH3 will not work.
  • The default port for the namenode plugins has changed from 9090 to 10090.

2. Application Compatibility

The core Hadoop communication layer (to HDFS and JobTracker) now has support for passing security credentials. A few low level APIs have changed, but most applications should not be affected.
