Balu Vellanki updated FALCON-634:
---------------------------------
Assignee: Sowmya Ramesh
> Add server side extensions in Falcon
> ------------------------------------
>
> Key: FALCON-634
> URL: https://issues.apache.org/jira/browse/FALCON-634
> Project: Falcon
> Issue Type: New Feature
> Affects Versions: 0.6
> Reporter: Venkatesh Seetharam
> Assignee: Sowmya Ramesh
> Labels: recipes
> Fix For: 0.10
>
>
> 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.
