Hue 3.8 brings a new way to directly submit Spark jobs from a Web UI. Last year we released Spark Igniter to enable developers to submit Spark jobs through a Web Interface. While this approach worked, the UX left a lot to be desired. Programs had to implement an interface, be compiled beforehand and YARN support was lacking. We also wanted to add support for Python and Scala, focusing on delivering an interactive and iterative programming experience similar to using a REPL.…

Hive did a big jump by finally graduating to its 1.0 version version. It is even 1.1 now (equivalent to 0.14).

Need for Speed! In the soon to be released Hue 3.8, we have added the ability to serve Hue’s static files (images, JavaScript, and etc) with an external server like NGINX. This allows us to dramatically cut down on the number of files served by the Hue application, making the whole user experience dramatically faster. For example, in the old version of Hue, rendering the beeswax application on demo.gethue.com performs 73 requests in 3 seconds to download 2.…

This is quite useful if you want for instance to show a disclaimer to your users, or to clearly mark a testing or production environment, or if you want to display some dynamic information there. Depending on if you are using Cloudera Manager or not, you should either add a safety valve or edit a .…

Hue comes with an HBase App that lets you create table, search for rows, read cell content… in just a few clicks. We are now glad to release the last missing piece of security (available in the upcoming Hue 3.8) for making the app production ready! The HBase app talks to HBase through a proxy server (called Thrift Server V1) which forwards the commands to HBase. Because Hue stands between the proxy server and the actual user, the proxy server thinks that all the operations (e.…
