CDAP provides these\nessential capabilities:\n\n- Abstraction of data in the Hadoop environment through logical representations of underlying data;\n- Portability of applications through decoupling underlying infrastructures;\n- Services and tools that enable faster application creation in development;\n- Integration of the components of the Hadoop ecosystem into a single platform;\n- Metadata management that automatically captures metadata and lineage;\n- CDAP pipelines with an integrated UI for click-and-drag development; and\n- Higher degrees of operational control in production through enterprise best-practices.\n\nCDAP exposes developer APIs (Application Programming Interfaces) for creating applications\nand accessing core CDAP services. CDAP defines and implements a diverse collection of\nservices that land applications and data on existing Hadoop infrastructure such as HBase,\nHDFS, YARN, MapReduce, Hive, and Spark.\n\nYou can run applications ranging from simple MapReduce Jobs and complete ETL (extract,\ntransform, and load) pipelines all the way up to complex, enterprise-scale data-intensive\napplications.\n\nDevelopers can build and test their applications end-to-end in a full-stack, single-node\ninstallation. CDAP can be run either as a Sandbox, deployed within the Enterprise \non-premises or hosted in the Cloud.\n\nFor more information, see our collection of `Developers' Manual and other documentation\n\u003chttp://docs.cask.co/cdap/current/en/developers-manual/index.html\u003e`__.\n\n\nGetting Started\n===============\n\nPrerequisites\n-------------\n\nTo install and use CDAP, there are a few simple prerequisites:\n\n1. JDK 8+ (required to run CDAP; note that $JAVA_HOME should be set)\n#. `Node.js \u003chttps://nodejs.org/\u003e`__ (required to run the CDAP UI; we recommend any version greater than v4.5.0)\n#. Apache Maven 3.0+ (required to build the example applications; 3.1+ to build CDAP itself)\n\nBuild\n-----\n\nYou can get started with CDAP by building directly from the latest source code::\n\n  git clone https://github.com/caskdata/cdap.git\n  cd cdap\n  mvn clean package\n\nAfter the build completes, you will have built all modules for CDAP.\n\nFor more build options, please refer to the `build instructions \u003cBUILD.rst\u003e`__.\n\n\nIntroductory Tutorial\n=====================\n\nVisit our web site for an `introductory tutorial for developers\n\u003chttp://docs.cask.co/cdap/current/en/developers-manual/getting-started/index.html\u003e`__ that\nwill guide you through installing CDAP and running an example application.\n\n\nWhere to Go Next\n================\n\nNow that you've had a look at the CDAP Sandbox, take a look at:\n\n- Developers' Manual, located in the source distribution in ``cdap-docs/developers-manual/source``\n  or `online \u003chttp://docs.cask.co/cdap/current/en/developers-manual/index.html\u003e`__.\n- `CDAP Releases and timeline \u003chttp://docs.cask.co/cdap/index.html\u003e`__\n\n\nHow to Contribute\n=================\n\nInterested in helping to improve CDAP? We welcome all contributions, whether in filing\ndetailed bug reports, submitting pull requests for code changes and improvements, or by\nasking questions and assisting others on the mailing list.\n\nFor quick guide to getting your system setup to contribute to CDAP, take a look at our\n`Contributor Quickstart Guide \u003cDEVELOPERS.rst\u003e`__.\n\nFiling Issues: Bug Reports \u0026 Feature Requests\n---------------------------------------------\nBugs and suggestions should be made by `filing an issue \u003chttps://issues.cask.co/browse/cdap\u003e`__.\n\nExisting issues can be browsed at `the CDAP project issues\n\u003chttps://issues.cask.co/browse/CDAP-8373?jql=project%20%3D%20CDAP\u003e`__.\n\nPull Requests\n-------------\n\nWe have a simple pull-based development model with a consensus-building phase, similar to\nApache's voting process. If you’d like to help make CDAP better by adding new features,\nenhancing existing features, or fixing bugs, here's how to do it:\n\n1. If you are planning a large change or contribution, discuss your plans on the\n   `cdap-dev@googlegroups.com \u003chttps://groups.google.com/d/forum/cdap-dev\u003e`__ mailing list first.\n   This will help us understand your needs and best guide your solution in a way that fits the project.\n2. Fork CDAP into your own GitHub repository.\n3. Create a topic branch with an appropriate name.\n4. Work on the code to your heart's content.\n5. Once you’re satisfied, create a pull request from your GitHub repo (it’s helpful if you fill in\n   all of the description fields).\n6. After we review and accept your request, we’ll commit your code to the caskdata/cdap repository.\n\nThanks for helping to improve CDAP!\n\nMailing Lists\n-------------\n\nCDAP User Group and Development Discussions:\n\n- `cdap-user@googlegroups.com \u003chttps://groups.google.com/d/forum/cdap-user\u003e`__\n\nThe *cdap-user* mailing list is primarily for users using the product to develop\napplications. You can expect questions from users, release announcements, and any other\ndiscussions that we think will be helpful to the users.\n\n- `cdap-dev@googlegroups.com \u003chttps://groups.google.com/d/forum/cdap-dev\u003e`__\n\nThe *cdap-dev* mailing list is essentially for developers actively working\non the product, and should be used for all our design, architecture and technical\ndiscussions moving forward. This mailing list will also receive all JIRA and GitHub\nnotifications.\n\n\nLicense and Trademarks\n======================\n\nCopyright © 2014-2017 Cask Data, Inc.\n\nLicensed under the Apache License, Version 2.0 (the \"License\"); you may not use this file except\nin compliance with the License.
