> *Recipe Listing*
> A GET method may be added to the Prism server on a new Jersey resource to list recipes and their corresponding root location on recipe repository. Corresponding CLI methods to be present
> {noformat}
> [hrt_qa@node-1 recipe]$ falcon recipe -list
> List of recipes
> {
>   "totalSize": 2,
>   "results": {
>     "hdfs-replication": "hdfs://node-1.example.com:8020/apps/falcon/recipe/hdfs-replication",
>     "hive-disaster-recovery": "hdfs://node-1.example.com:8020/apps/falcon/recipe/hive-disaster-recovery"
>   }
> }
> {noformat}
> *Get resources of a given recipe*
> List all the resources of a given recipe
> {noformat}
> [hrt_qa@node-1 recipe]$ falcon recipe -getResources -name hdfs-replication

> *Recipe Description*
> A GET method may be added to the Prism server to echo the README as documentation for the users. This may contain brief on the functionality offered by the recipe and any operability notes of importance
> {noformat}
> [hrt_qa@node-1 recipe]$ falcon recipe -describe -name hdfs-replication
> HDFS Directory Replication Recipe
> Overview
> This recipe implements replicating arbitrary directories on HDFS from one
> Hadoop cluster to another Hadoop cluster.
> This piggy backs on replication solution in Falcon which uses the DistCp tool.
> Use Case
> * Copy directories between HDFS clusters with out dated partitions
> * Archive directories from HDFS to Cloud. Ex: S3, Azure WASB
> Limitations
> As the data volume and number of files grow, this can get inefficient.
> {noformat}
