Ajay Yadava commented on FALCON-1105:
-------------------------------------
[~sowmyaramesh] Seems like a non-trivial patch, can you please add it to
reviewboard?
Also, irrespective of where the resources go (depending on the choice we make
in FALCON-1108), CLI side of recipe code should be separated from existing one
as it's turning into one large monolithic piece of code. You can refer
FalconMetaDataCLI for reference.
Will review it completely once you upload the patch to reviewboard.

> *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}
