You might have already all the pre-requisites installed but we are going to show how to start from a fresh Yosemite (10.10) or El Capitan (10.11) install and end up with running Hue on your Mac in almost no time! We are going to be using the official Quickstart VM from Cloudera that already packs all the Hadoop ecosystem components your Hue will talk to. If you don’t have the latest already downloaded and running, please visit this link and choose the versions that suits you the best.…

The Solr Search App is having a great success and users often wonder if they could use it without the Hadoop related apps. As the app is only using the standard Apache Solr REST API and Hue allows to customize which apps to show, the answer is yes! Note: this is an alternative to configure the groups and application permissions directly in the User Admin.  1. Install Hue from the links on the ‘Download’ section menu…

August 7th 2015 update: this post is now deprecated as of Hue 3.9: Exporting and importing Oozie workflows directly from the UI There is no handy way to import and export your Oozie workflows until Hue 4 and HUE-1660, but here is a manual workaround possible since Hue 3.8/CDH5.4 and its new Oozie Editor. The previous methods were very error prone as they required to insert data in multiple tables at the same time.…

Last update: March 3rd 2016  Hue comes with a set of commands for simplifying the management of the service. Here is a quick guide about how to use them.  Get started If using CM, export this variable in order to point to the correct Hue: cd /opt/cloudera/parcels/CDH/lib/ 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. If not using CM, just append the root of Hue home, normally:…

Hello / Kumusta! After Central America at the beginning of winter, it was again the perfect timing for one more exotic location: the Phillipines! The team flew to the other side of the world on the island of Boracay for some great tricycle action, kitesurfing and discovering some new culture and food:  Onwards!! Hue Team

Update August 2015: It is not much easier to import or export your dashboards, it is the same interface as the Oozie workflows exporter.  Using Hue 3.8 or CDH5.4 20000013 is the id you can see in the URL of the dashboard. If you don't specify -pks it will export all your dashboards. ./build/env/bin/hue dumpdata search.Collection -indent 2 -pks=20000013 -natural data.json Using Hue 3.7 or less ./build/env/bin/hue dumpdata search -indent 2 data.…

December 8th 2015 update: this post is now deprecated as of Hue 3.9: https://gethue.com/automatic-high-availability-and-load-balancing-of-hue-in-cloudera-manager-with-monitoring/</a></em></span> By default, Hue installs on a single machine, which means Hue is both constrained to that machine’s CPU and memory, which can limit the total number of active users before Hue becomes unstable. Furthermore, even a lightly loaded machine could crash, which would bring Hue out of service. This tutorial demonstrates hue-lb-example, an example load balancer that can automatically configure NGINX and HAProxy for a Cloudera Manager-managed Hue.…
