These declarative configurations are expressed in such a way that the dependencies between
these configured entities are explicitly described. This information about inter-dependencies
between various entities allows Falcon to orchestrate and manage various data management functions.

Complex functions such as retrying failures, identifying possible SLA breaches or automated
handling of input data changes are now simple directives. All the administrative functions
and user level functions are available via RESTful APIs. CLI is simply a wrapper over the

> Hadoop and its ecosystem of products have made storing and processing massive amounts
of data commonplace. This has enabled numerous organizations to gain valuable insights that
they never could have achieved in the past. While it is easy to leverage Hadoop for crunching
large volumes of data, organizing data, managing life cycle of data and processing data is
fairly involved. This is solved adequately well in a classic data platform involving data
warehouses and standard ETL (extract-transform-load) tools, but remains largely unsolved today.
In addition to data processing complexities, Hadoop presents new sets of challenges and opportunities
relating to management of data.
> Data Management on Hadoop encompasses data motion, process orchestration, lifecycle management,
data discovery, etc. among other concerns that are beyond ETL. Falcon is a new data processing
and management platform for Hadoop that solves this problem and creates additional opportunities
by building on existing components within the Hadoop ecosystem (ex. Apache Oozie, Apache Hadoop
DistCp etc.) without reinventing the wheel. Falcon has been in production at InMobi, going
on its second year and has been managing hundreds of feeds and processes.

Hadoop will grow its community of users by increasing the places Hadoop can be utilized and
the use cases it will solve. By developing Falcon in Apache we hope to gather a diverse community
of contributors, helping to ensure that Falcon is deployable for a broad range of scenarios.
Members of the Hadoop development community will be able to influence Falcon’s roadmap,
and contribute to it. We believe having Falcon as part of the Apache Hadoop ecosystem will
be a great benefit to all of Hadoop's users.

A version with a valuable set of features is developed by the list of initial committers and
is hosted on github.
> === Meritocracy ===
> Our intent with this incubator proposal is to start building a diverse developer community
around Falcon following the Apache meritocracy model. We have wanted to make the project open
source and encourage contributors from multiple organizations from the start. We plan to provide
plenty of support to new developers and to quickly recruit those who make solid contributions
to committer status.
> === Community ===
> We are happy to report that the initial team already represents multiple organizations.
We hope to extend the user and developer base further in the future and build a solid open
source community around Falcon.
> === Core Developers ===
> Falcon is currently being developed by three engineers from InMobi – Srikanth Sunderrajan,
Shwetha G S, and Shaik Idris, two Hortonworks employees – Sanjay Radia and Venkatesh Seetharam.
In addition, Rohini Palaniswamy and Thiruvel Thirumoolan, were also involved in the initial
design discussions. Srikanth, Shwetha and Shaik are the original developers. All the engineers
have built two generations of Data Management on Hadoop, having deep expertise in Hadoop and
are quite familiar with the Hadoop Ecosystem. Samarth Gupta & Rishu Mehrothra, both from
InMobi have build the QA automation for Falcon.
> === Alignment ===
> The ASF is a natural host for Falcon given that it is already the home of Hadoop, Pig,
Knox, HCatalog, and other emerging “big data” software projects. Falcon has been designed
to solve the data management challenges and opportunities of the Hadoop ecosystem family of
products. Falcon fills the gap that Hadoop ecosystem has been lacking in the areas of data
processing and data lifecycle management.

has been contributing patches to Apache Hadoop and Apache Oozie, Shwetha GS has been contributing
patches to Apache Oozie.  Seetharam Venkatesh is a committer on Apache Knox. Sharad Agarwal,
Amareshwari SR (also a Apache Hive PMC member) and Sanjay Radia are PMC members on Apache

project following an established development model. We have also given reasons in the Rationale
