Hue 3.5+ ships with two font icon sets: Font Awesome 4 (http://fontawesome.io/) and the Hue Filetypes font that includes some basic file types you might need. The icons are available in the Hue master or in this zip file: When you want to use the new icons in your app, you have first to import the Hue Filetypes css in your .mako template:  <link href="/static/ext/css/hue-filetypes.css" rel="stylesheet"> and then define you icons with the same way you would do with Font Awesome.…

Last update on March 9 2016  First, backup the database. By default this is this SqlLite file: cp /var/lib/hue/desktop.db ~/ Then if using CM, export this variable in order to point to the correct database: HUE_CONF_DIR=/var/run/cloudera-scm-agent/process/-hue-HUE_SERVER-id echo $HUE_CONF_DIR export HUE_CONF_DIR Where is the most recent ID in that process directory for hue-HUE_SERVER. A quick way to get the correct directory is to use this script: export HUE_CONF_DIR="/var/run/cloudera-scm-agent/process/\`ls -alrt /var/run/cloudera-scm-agent/process | grep HUE | tail -1 | awk '{print $9}'\`"…

With the release of django-pygresql, the Hue team has taken a first stab at PyGreSQL support in Django! The ‘Why’ The open source world has many different kinds of licenses and it can be confusing to know which one makes sense for you.

Completed in Thailand, HUE-826 brings a new way to integrate external Web application into Hue. Java apps or already existing websites can now be shown as a Hue app with little effort.    For example, let’s integrate Tableau: To create a new app: build/env/bin/hue create_proxy_app my_hue http://gethue.com tools/app_reg/app_reg.py --install my_hue --relative-paths If you want to update the url later, change it in the ini: [my_hue] url=http://gethue.com As usual feel free to comment on the hue-user list or @gethue!…

In this tutorial, we’ll be exploring the different options available for altering passwords in Hue using the default authentication backend (AllowFirstUserBackend). User Interface Users can change their passwords via the “” -> “Edit Profile” found in the top-right corner of Hue.If a user cannot remember their password, the Hue administrator can change it for them via the user manager.…

A new SAML 2.0 backend is under development to provide a better authentication experience in Hue. Rather than signing in using Hue credentials, single sign-on (SSO) authentication can be achieved with this new backend. The Basics In SAML 2.0, there are 2 basic components: the Service Provider (SP) and Identity Provider (IdP). The typical flow from SP to IdP is made obvious in following image. SAML architecture from http://en.…

In the previous posts we focused on some [new features][1] and how to quickly analyze your [data][2] with the Hive editor. This time, we are going to follow-up on Hue authentication mechanisms. We previously described a [list of backends][3] like LDAP, AllowAll (improved recently in the latest [2.…
