    Description

      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().)
