Hue is a web interface for Apache Hadoop that makes common Hadoop tasks such as running MapReduce jobs, browsing HDFS, and creating Apache Oozie workflows, easier. In this post, we’re going to focus on the dynamic workflow builder that Hue provides for Oozie that will be released in Hue 2.2.0 (For a high-level description of Oozie integration in Hue, see this blog post).
Hue is a web interface for Apache Hadoop that makes common Hadoop tasks such as running MapReduce jobs, browsing HDFS, and creating Apache Oozie workflows, easier. (To learn more about the integration of Oozie and Hue, see this blog post.) In this post, we’re going to focus on how one of the fundamental components in Hue, Useradmin, has matured.
New User and Permission Features
User and permission management in Hue has changed drastically over the past year.
Hue is a Web-based interface that makes it easier to use Apache Hadoop. Hue 2.1 (included in CDH4.1) provides a new application on top of Apache Oozie (a workflow scheduler system for Apache Hadoop) for creating workflows and scheduling them repetitively. For example, Hue makes it easy to group a set of MapReduce jobs and Hive scripts and run them every day of the week.
Yesterday’s post gave an overview of the HUE (aka. Hadoop User Experience) project which was released in CDH3b2 and available on github. HUE is a graphical “desktop” style web application that runs in modern browsers (Firefox, Chrome, Safari, and IE8+) that allows users to interact with a Hadoop installation as if it were just another computer. They browse the file system, create and manage user accounts, view and edit files,
The HUE (aka. Hadoop User Experience) project [download|installation|manual] started as Cloudera Desktop about a year ago. The old name “Desktop” really refers to a desktop look-and-feel, since HUE is a web UI for Hadoop. Beyond delivering a suite of web applications, it is also a platform for building custom applications with a nice UI library. Gradually, we realized how much value such a UI platform would bring to the community,
