CDAP is an integrated, open source application development platform for the Hadoop ecosystem that provides developers with data and application abstractions to simplify and accelerate application development, address a broader range of real-time and batch use cases, and deploy applications into production while satisfying enterprise requirements.
CDAP is a layer of software running on top of Apache Hadoop® platforms such as the Cloudera Enterprise Data Hub or the Hortonworks® Data Platform. CDAP provides these essential capabilities:
CDAP exposes developer APIs (Application Programming Interfaces) for creating applications and accessing core CDAP services. CDAP defines and implements a diverse collection of services that land applications and data on existing Hadoop infrastructure such as HBase, HDFS, YARN, MapReduce, Hive, and Spark.
You can run applications ranging from simple MapReduce Jobs and complete ETL (extract, transform, and load) pipelines all the way up to complex, enterprise-scale data-intensive applications.
Developers can build and test their applications end-to-end in a full-stack, single-node installation. CDAP can be run either as a Sandbox, deployed within the Enterprise on-premises or hosted in the Cloud.
For more information, see our collection of
Developers' Manual and other documentation__.
To install and use CDAP, there are a few simple prerequisites:
Node.js_ (required to run the CDAP UI; we recommend any version greater than v4.5.0) #. Apache Maven 3.0+ (required to build the example applications; 3.1+ to build CDAP itself)
You can get started with CDAP by building directly from the latest source code::
git clone https://github.com/caskdata/cdap.git cd cdap mvn clean package
After the build completes, you will have built all modules for CDAP.
For more build options, please refer to the
Visit our web site for an
introductory tutorial for developers__ that will guide you through installing CDAP and running an example application.

We have a simple pull-based development model with a consensus-building phase, similar to Apache's voting process. If you’d like to help make CDAP better by adding new features, enhancing existing features, or fixing bugs, here's how to do it:
Thanks for helping to improve CDAP!
CDAP User Group and Development Discussions:
The cdap-user mailing list is primarily for users using the product to develop applications. You can expect questions from users, release announcements, and any other discussions that we think will be helpful to the users.
The cdap-dev mailing list is essentially for developers actively working on the product, and should be used for all our design, architecture and technical discussions moving forward. This mailing list will also receive all JIRA and GitHub notifications.
