             Summary: Add recipes in Falcon
                 Key: FALCON-634
                 URL: https://issues.apache.org/jira/browse/FALCON-634
             Project: Falcon
          Issue Type: Bug
    Affects Versions: 0.6
            Reporter: Venkatesh Seetharam


Falcon offers many services OOTB and caters to a wide array of use cases. However, there has been many asks that does not fit the functionality offered by Falcon. I'm proposing that we add recipes to Falcon which is similar to recipes in Whirr and other management solutions such as puppet and chef.

Overview:
A recipe essentially is a static process template with parameterized workflow to realize a specific use case. For example:

* replicating directories from one HDFS cluster to another (not timed partitions)
* replicating hive metadata (database, table, views, etc.)
* replicating between HDFS and Hive - either way
* anonymization of data based on schema
* data masking
* etc.

Proposal:
Falcon provides a Process abstraction that encapsulates the configuration 
for a user workflow with scheduling controls. All recipes can be modeled 
as a Process with in Falcon which executes the user workflow 
periodically. The process and its associated workflow are parameterized. The user will provide a properties file with name value pairs that are substituted by falcon before scheduling it.

This is a client side concept. The server does not know about a recipe but only accepts the cooked recipe as a process entity. 

The CLI would look something like this:
falcon -recipe $recipe_name -properties $properties_file

Recipes will reside inside addons (contrib) with source code and will have an option to package 'em.
