> RBF: Adding missing ClientProtocol methods to RBF
> -------------------------------------------------
>
> Key: HDFS-13655
> URL: https://issues.apache.org/jira/browse/HDFS-13655
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Xiao Chen
> Priority: Major
>
> As discussed with [~elgoiri], there are some HDFS methods that does not take
> path as a parameter. We should support these to work with federation.
> The ones missing are:
> * Snapshots
> * Storage policies
> * Encryption zones
> * Cache pools
> One way to reasonably have them to work with federation is to 'list' each
> nameservice and concat the results. This can be done pretty much the same as
> {{refreshNodes()}} and it would be a matter of querying all the subclusters
> and aggregate the output (e.g., {{getDatanodeReport()}}.)
