This new feature, jointly developed by Cloudera and Intel engineers, makes management of role-based security much easier in Apache Hive, Impala, and Hue.
Apache Sentry (incubating) provides centralized authorization for services and applications in the Apache Hadoop ecosystem, allowing administrators to set up granular, role-based protection on resources, and to review them in one place. Previously, Sentry only designated administrators to
REVOKE privileges on an authorizable object. In Apache Sentry 1.5.0 (shipping inside CDH 5.2), we have implemented a new feature (SENTRY-327) that allows admin users to delegate the
GRANT privilege to other users using
WITH GRANT OPTION. If a user has the
GRANT OPTION privilege on a specific resource, the user can now grant the
GRANT privilege to other users on the same resource. Apache Hive, Impala, and Hue have all been updated to take advantage of this new Sentry functionality.
An improved Search app in Hue 3.6 makes the Hadoop user experience even better.
Hue 3.6 (now packaged in CDH 5.1) has brought the second version of the Search App up to even higher standards. The user experience has been greatly improved, as the app now provides a very easy way to build custom dashboards and visualizations.
Get started with Apache Hadoop and use-case examples online in just seconds.
Today, we announced Cloudera Live, a new online service for developers and analysts (currently in public beta) that makes it easy to learn, explore, and try out CDH, Cloudera’s open source software distribution containing Apache Hadoop and related projects. No downloads, no installations, no waiting — just point-and-play!
Our thanks to Amar Parkash, a Software Developer at Goibibo, a leading travel portal in India, for the enthusiastic support of Hue you’ll read below.
At Goibibo, we use Hue in our production environment. I came across Hue while looking for a near real-time log search tool and got to know about Cloudera Search and the interface provided by Hue. I tried it on my machine and was really impressed by the UI it provides for Apache Hive, Apache Pig, HDFS, job browser, and basically everything in the Big Data domain. We immediately deployed Hue in production, and that has been one of the best decisions we have ever made for our data platform at Goibibo.
Hue users can learn a lot about new features by following a steady stream of new demos.
Hue, the open source Web UI that makes Apache Hadoop easier to use, is now a standard across the ecosystem — shipping within multiple software distributions and sandboxes. One of the reasons for its success is an agile developer community behind it that is constantly rolling out new features to its users.
Integrating Hue with LDAP can help make your secure Hadoop apps as widely consumed as possible.
Hue, the open source Web UI that makes Apache Hadoop easier to use, easily integrates with your corporation’s existing identity management systems and provides authentication mechanisms for SSO providers. So, by changing a few configuration parameters, your employees can start analyzing Big Data in their own browsers under an existing security policy.
In this installment of “Meet the Engineer” we speak with Romain Rigaux, a Software Engineer on the Hue team.
What do you do at Cloudera, and in which project are you involved?
Currently I work on Hue, the open source Web interface that lets users do Big Data analysis directly from their browser. Its goal is to make that process easier, so that more users can get more insights, more quickly.
The team behind Hue, the open source Web UI that makes Apache Hadoop easier to use, strikes again with a new Spark app.

You can use Hue and Cloudera Search to build your own integrated Big Data search app.
In a previous post, you learned how to analyze data using Apache Hive via Hue’s Beeswax and Catalog apps. This time, you’ll see how to make Yelp Dataset Challenge data searchable by indexing it and building a customizable UI with the Hue Search app.
Indexing Data in Cloudera Search
Hue, the open source Web UI that makes Apache Hadoop easier to use, has a brand-new application that enables transferring data between relational databases and Hadoop. This new application is driven by Apache Sqoop 2 and has several user experience improvements, to boot.
Sqoop is a batch data migration tool for transferring data between traditional databases and Hadoop. The first version of Sqoop is a heavy client that drives and oversees data transfer via MapReduce. In Sqoop 2, the majority of the work was moved to a server that a thin client communicates with. Also, any client can communicate with the Sqoop 2 server over its JSON-REST protocol. Sqoop 2 was chosen instead of its predecessors because of its client-server design.
