¡Hola! The Hue project recently got its biggest release. It was once again time to celebreate and also prepare the next big thing 🙂 For the first time, a European location was picked: Tenerife, in the Canary Islands! Similarly to the previous retreat in Hawaii, the team could enjoy a great island with a Volcano, warm water, sun, sea food, tapas, wind & kitesurfing. At the end of the week, the team was recharged, the core of the new Oozie App for creating workflows was done, and much more is under way!…

This post was initially published on the Hue project blog https://gethue.com/bay-area-bike-share-data-analysis-with-spark-notebook-part-2/ Apache Spark is getting popular and Hue contributors are working on making it accessible to even more users. Specifically, by creating a Web interface that allows anyone with a browser to type some Spark code and execute it. A Spark submission REST API was built for this purpose and can also be leveraged by the developers. In a previous post, we demonstrated how to use Hue's Search app to seamlessly index and visualize trip data from Bay Area Bike Share and leverage Spark to supplement that analysis by adding weather data to our dashboard.…

The application received a lot of feedback and has been greatly improved. Here is a short video detailing all the new stuff:  You can see a quick summary of the main novelties below:  Top Bar It was re-organized in order to split widgets displaying records or facets.…

Hi Hadoop Sheriffs, In order to support the growth of the Apache Sentry project and make it easier to secure your cluster, a new app was added into Hue. Sentry privileges determine which Hive / Impala databases and tables a user can see or modify. The Security App let’s you create/edit/delete Roles and Privileges directly from your browser (there is no sentry-provider.ini file to edit anymore). Here is a video showing how the app works:…

Hue is a lightweight Web server that lets you use Hadoop directly from your browser. Hue is just a ‘view on top of any Hadoop distribution’ and can be installed on any machine. There are multiples ways (cf. ‘Download’ section of gethue.com) to install Hue. The next step is then to configure Hue to point to your Hadoop cluster. By default Hue assumes a local cluster (i.e. there is only one machine) is present.…

This blog post was originally published on the MapR blog. While big data security analytics promises to deliver great insights in the battle against cyber threats, the concept and the tools are still maturing. In this blog, I’ll simplify the topic of adopting security in Hadoop by showing you how to encrypt traffic between Hue and Hive. Hue can communicate with Hive over a channel encrypted with SSL. Let’s take a look at the interface and the handshake mechanism first before trying to secure it.…
