Hue lets you interact with Hadoop services from within your browser without having to go to a command-line interface. It features a file browser for HDFS, an Apache Oozie Application for creating workflows of data processing jobs, a job designer/browser for MapReduce,

Today, many (if not most) companies have ETL or data enrichment jobs that are executed on a regular basis as data becomes available. In this scenario it is important to minimize the lag time between data being created and being ready for analysis.
CDH, Cloudera’s open-source distribution of Apache Hadoop and related projects,
For several good reasons, 2013 is a Happy New Year for Apache Hadoop enthusiasts.
In 2012, we saw continued progress on developing the next generation of the MapReduce processing framework (MRv2), work that will bear fruit this year. HDFS experienced major progress toward becoming a lights-out, fully enterprise-ready distributed filesystem with the addition of high availability features and increased performance. And a hint of the future of the Hadoop platform was provided with the Beta release of Cloudera Impala,
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).

As Apache Oozie, the workflow engine for Apache Hadoop, continues to receive wider adoption from our customers and the community, we’re seeing patterns with respect to the biggest challenges for users. One such point of difficulty is setting up and using Oozie’s ShareLib for allowing JARs to be shared by different workflows.
