             Summary: IGFS: Some operations on DUAL file system could be passed directly to secondary fiel system.
                 Key: IGNITE-2812
                 URL: https://issues.apache.org/jira/browse/IGNITE-2812
             Project: Ignite
          Issue Type: Task
          Components: IGFS
    Affects Versions: 1.5.0.final
            Reporter: Vladimir Ozerov
             Fix For: 1.7


*Problem*
When working in DUAL mode, some operations delegate to secondary file system even if all necessary information is already in IGFS. Example: "list paths" operation. It has to consult to secondary file system because we are not sure that all existing entries exists in meta cache. As such, we always delegate to secondary file system.

*Proposed solution*
Probably we can route such operations directly to seconday FS without involving IGFS. This will save us several network trips.
