Cloudera Enterprise 5.10 includes the latest updates of Hue, the intelligent editor for SQL Developers and Analysts.
As part of Cloudera’s continuing investments in user experience and productivity, Cloudera Enterprise 5.10 includes an updated version of Hue. We provide a summary of the main enhancements in the following part of this blog post. (Hue from C5.10 is also available for a quick try in one click on demo.gethue.com.)
The Hue editor keeps getting better with these major improvements:

Updated 11/22/16 – Important: All features below are working on CDH 5.9.0 and CM 5.9.0 and above.
This tool makes Oozie migrations off Apache Derby (or any other supported database) easy, in addition to streamlining upgrades.
The Apache Oozie server is a stateless web application by design, with all information about running and completed workflows, coordinator jobs, and bundle jobs stored in a relational database.
The internals of Oozie’s ShareLib have changed recently (reflected in CDH 5.0.0). Here’s what you need to know.
In a previous blog post about one year ago, I explained how to use the Apache Oozie ShareLib in CDH 4. Since that time, things have changed about the ShareLib in CDH 5 (particularly directory structure), so some of the previous information is now obsolete. (These changes went upstream under OOZIE-1619.)
In this post I’ll explain those changes.
Improved scheduling capabilities via Oozie in CDH 5 makes for far fewer headaches.
One of the best new Apache Oozie features in CDH 5, Cloudera’s software distribution, is the ability to use cron-like syntax for coordinator frequencies. Previously, the frequencies had to be at fixed intervals (every hour or every two days, for example) – making scheduling anything more complicated (such as every hour from 9am to 5pm on weekdays or the second-to-last day of every month) complex and difficult.
Oozie’s new HA qualities help cluster operators sleep well at night. Here’s how it works.
One of the big new features in CDH 5 for Apache Oozie is High Availability (HA). In designing this feature, the Oozie team at Cloudera had two main goals: 1) Don’t change the API or usage patterns, and 2) the user shouldn’t even have to know that HA is enabled. In other words, we wanted Oozie HA to be as easy and transparent as possible.
