Hadoop/HBase Tasks
------------------

- upload: write files + upload || direct call || ???
- access: which language (many access languages available)
- ELSSI: large part of it deals with Oracle -> should be replaced
           (by agnostic layer talking to storage-specific service)
         ELSSI -> SelectionSvc -> H/H || Oracle 
         CLI   -> SelectionSvc
         agree on calls API (XML passed arround, stored in LoggingSvc)
