A framework for managing data life cycle in Hadoop clusters
Apache™ Falcon addresses enterprise challenges related to Hadoop data replication, business continuity, and lineage tracing by deploying a framework for data management and processing. Falcon centrally manages the data lifecycle, facilitate quick data replication for business continuity and disaster recovery and provides a foundation for audit and compliance by tracking entity lineage and collection of audit logs.
Falcon allows an enterprise to process a single massive dataset stored in HDFS in multiple ways—for batch, interactive and streaming applications. With more data and more users of that data, Apache Falcon’s data governance capabilities play a critical role. As the value of Hadoop data increases, so does the importance of cleaning that data, preparing it for business intelligence tools, and removing it from the cluster when it outlives its useful life.
Falcon simplifies the development and management of data processing pipelines with a higher layer of abstraction, taking the complex coding out of data processing applications by providing out-of-the-box data management services. This simplifies the configuration and orchestration of data motion, disaster recovery and data retention workflows.
The Falcon framework can also leverage other HDP components, such as Pig, HDFS, and Oozie. Falcon enables this simplified management by providing a framework to define, deploy, and manage data pipelines.
Apache Falcon meets enterprise data governance needs in three areas:
|Centralized data lifecycle management||
|Compliance and audit||
|Database replication and archival||
Hadoop operators can use the Falcon web UI or the command-line interface (CLI) to create data pipelines, which consist of cluster storage location definitions, dataset feeds, and processing logic.
Each pipeline consists of XML pipeline specifications, called entities. These entities act together to provide a dynamic flow of information to load, clean, and process data.
There are three types of entities:
Each entity is defined separately and then linked together to form a data pipeline. Falcon provides predefined policies for data replication, retention, late data handling, and replication. These sample policies are easily customized to suit your needs.
The Apache Falcon community is working to enhance operations, support for transactional applications and improved tooling.

Introduction Hadoop has always been associated with BigData, yet the perception is it’s only suitable for high latency, high throughput queries. With the contribution of the community, you can use Hadoop interactively for data exploration and visualization. In this tutorial you’ll learn how to analyze large datasets using Apache Hive LLAP on Amazon Web Services […]
A very common request from many customers is to be able to index text in image files; for example, text in scanned PNG files. In this tutorial we are going to walkthrough how to do this with SOLR. Prerequisites Download the Hortonworks Sandbox Complete the Learning the Ropes of the HDP Sandbox tutorial. Step-by-step guide […]
Introduction In this tutorial, you will learn about the different features available in the HDF sandbox. HDF stands for Hortonworks DataFlow. HDF was built to make processing data-in-motion an easier task while also directing the data from source to the destination. You will learn about quick links to access these tools that way when you […]
Introduction JReport is a embedded BI reporting tool can easily extract and visualize data from the Hortonworks Data Platform 2.3 using the Apache Hive JDBC driver. You can then create reports, dashboards, and data analysis, which can be embedded into your own applications. In this tutorial we are going to walkthrough the folllowing steps to […]
Apache Zeppelin on HDP 2.4.2 Author: Vinay Shukla In March 2016 we delivered the second technical preview of Apache Zeppelin, on HDP 2.4. Meanwhile we and the Zeppelin community have continued to add new features to Zeppelin. These features are now available in the final technical preview of Apache Zeppelin. This technical preview works with […]
The Hortonworks Sandbox is delivered as a Dockerized container with the most common ports already opened and forwarded for you. If you would like to open even more ports, check out this tutorial.
Introduction R is a popular tool for statistics and data analysis. It has rich visualization capabilities and a large collection of libraries that have been developed and maintained by the R developer community. One drawback to R is that it’s designed to run on in-memory data, which makes it unsuitable for large datasets. Spark is […]
