Enabling SSO Authentication in Hue

There’s good news for users of Hue, the open source web UI that makes Apache Hadoop easier to use: A new SAML 2.0-compliant backend, which is scheduled to ship in the next release of the Cloudera platform, will provide a better authentication experience for users as well as IT.

With this new feature, single sign-on (SSO) authentication can be achieved instead of using Hue credentials – thus, user credentials can be managed centrally (a big benefit for IT), and users needn’t log in to Hue if they have already logged in to another Web application sharing the SSO (a big benefit for users).

Explore the Impala App in Hue

The following post was originally published by the Hue Team at the Hue blog in a slightly different form.

Hue, the open source web GUI that makes Apache Hadoop easy to use, has supported Cloudera Impala since its inception to enable fast, interactive SQL queries from within your browser. In this post, you’ll see a demo of Hue’s Impala app in action and explore its impressive query speed for yourself.

How-to: Manage HBase Data via Hue

The following post was originally published by the Hue Team at the Hue blog in a slightly different form.

In this post, we’ll take a look at the new Apache HBase Browser App added in Hue 2.5 and which has improved significantly since then. To get the Hue HBase browser, grab Hue via CDH 4.4 packages, via Cloudera Manager, or build it directly from GitHub.

How-to: Achieve Higher Availability for Hue

Few projects within the Apache Hadoop umbrella have as much end-user visibility as Hue, the open source Web UI that makes Hadoop easier to use. Due to the great number of potential end users, it is useful to add a degree of fault tolerance to your deployment. This how-to describes how to achieve higher availability by placing several Hue instances behind a load balancer.


This tutorial demonstrates how to set up high availability by:

Demo: Using Hue to Access Hive Data Through Pig

This installment of the Hue demo series is about accessing the Hive Metastore from Hue, as well as using HCatalog with Hue. (Hue, of course, is the open source Web UI that makes Apache Hadoop easier to use.) 

What is HCatalog?

HCatalog is a module in Apache Hive that enables non-Hive scripts to access Hive tables. You can then directly load tables with Apache Pig or MapReduce without having to worry about re-defining the input schemas, or caring about or duplicating the data’s location.

What a Great Year for Hue Users!

HueWith the recent release of CDH 4.3, which contains Hue 2.3, I’d like to report on the fantastic progress of Hue in the past year.

For those who are unfamiliar with it, Hue is a very popular, end-user focused, fully open source Web UI designed for interaction with Apache Hadoop and its ecosystem components. Founded by Cloudera employees, Hue has been around for quite some time, but only in the last 12 months has it evolved into the great ramp-up and interaction tool it is today. It’s fair to say that Hue is the most popular open source GUI for the Hadoop ecosystem among beginners — as well as a valuable tool for seasoned Hadoop users (and users generally in an enterprise environment) – and it is the only end-user tool that ships with Hadoop distributions today. In fact, Hue is even redistributed and marketed as part of other user-experience and ramp-up-on-Hadoop VMs in the market.

Demo: The New Search App in Hue 2.4

In version 2.4 of Hue, the open source Web UI that makes Apache Hadoop easier to use, a new app was added in addition to more than 150 fixes: Search!

Using this app, which is based on Apache Solr, you can now search across Hadoop data just like you would do keyword searches with Google or Yahoo! In addition, a wizard lets you tweak the result snippets and tailors the search experience to your needs.

QuickStart VM: Now with Real-Time Big Data

For years, Cloudera has provided virtual machines that give you a working Apache Hadoop environment out-of-the-box. It’s the quickest way to learn and experiment with Hadoop right from your desktop.

We’re constantly updating and improving the QuickStart VM, and in the latest release there are two of Cloudera’s new products that give you easier and faster access to your data: Cloudera Search and Cloudera Impala. We’ve also added corresponding applications to Hue – an open source web-based interface for Hadoop, and the easiest way to interact with your data.

Demo: Apache Pig Editor in Hue 2.3

In the previous installment of the demo series about Hue — the open source Web UI that makes Apache Hadoop easier to use — you learned how to analyze data with Hue using Apache Hive via Hue’s Beeswax and Catalog applications. In this installment, we’ll focus on using the new editor for Apache Pig in Hue 2.3.

Complementing the editors for Hive and Cloudera Impala, the Pig editor provides a great starting point for exploration and real-time interaction with Hadoop. This new application lets you edit and run Pig scripts interactively in an editor tailored for a great user experience. Features include:

What’s New in Hue 2.3

We’re very happy to announce the 2.3 release of Hue, the open source Web UI that makes Apache Hadoop easier to use.

Hue 2.3 comes only two months after 2.2 but contains more than 100 improvements and fixes. In particular, two new apps were added (including an Apache Pig editor) and the query editors are now easier to use.
