Resolution: Duplicate
> IGFS: Some operations on DUAL file system could be passed directly to
> secondary file 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.
