Note: Sqoop2 is now replaced by https://gethue.com/importing-data-from-traditional-databases-into-hdfshive-in-just-a-few-clicks/  Apache Sqoop is a great tool for moving data (in files or databases) in or out of Hadoop. In Hue 3, a new app was added for making Sqoop2 easier to use. In this final episode (previous one was about Search) of the season 2 of the Hadoop Tutorial series let’s see how simple it becomes to export our Yelp results into a MySql table!…

Hue provides a Web interface for submitting Hive queries. Hue had its own server to service Hive queries called Beeswax. The more sophisticated and robust service, Apache HiveServer2, is supported as of Hue 2.5. Beeswax Hive Editor Thanks to HiveServer2 integration, Hue is getting the benefits from Sentry (How to configure Sentry Video). In addition to the security provided, Hue’s interface becomes more consistent. For example, a user without permissions on a database or table won’t see it in the query editor or in the Metastore app.…

The HBase app is an elegant way to visualize and search a lot of data. Apache HBase tables can be tricky to update as they require lower level API. Some good alternative for simplifying the data management or access is to use Apache Pig or Hive.  In this post we are going to show how to load our yelp data from the Oozie Bundles episode into HBase with Hive. Then we will use the HBase Browser to visualize it and Pig to compute some statistics.…

Now lets imagine that we also want to compute a top 10 and 100. How can we do this? One solution is to use Oozie bundles.    Workflow and Coordinator updates Bundles are are way to group coordinators together into a set.…

Hue is the web interface that improves the Apache Hadoop user experience. It’s a Django driven application and manages users accordingly. 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.…
