    Description

      ECSchemas will be configured and loaded only at the Namenode to avoid conflicts.
      Client has to specify one of these schemas during creation of ecZones.
      So, add an RPC to ClientProtocol to get all ECSchemas loaded at namenode, so that client can choose only any one of these.
