-------------------------------------
Resolution: Fixed
> IGFS: Disable default path modes by default.
> --------------------------------------------
>
> Key: IGNITE-3257
> URL: https://issues.apache.org/jira/browse/IGNITE-3257
> Project: Ignite
> Issue Type: Sub-task
> Components: IGFS
> Affects Versions: 1.6
> Reporter: Vladimir Ozerov
> Assignee: Vladimir Ozerov
> Priority: Critical
> Fix For: 1.7
>
>
> *Problem*
> We have a feature called "default path modes". When IGFS is started, it
> creates several special folder for each mode (PRIMARY, DUAL_SYNC, DUAL_ASYNC,
> PROXY).
> Our idea was that it would be convenient for users. However, in reality users
> are almost never need any of these directories, but:
> 1) It degrades Hadoop file system performance, as a path with "PROXY" mode
> forces secondary file system creation on the client.
> 2) It degrades path mode resolution performance on the server because we
> always has at least 4 modes to compare against.
> *Solution*
> Switch default flag for this property to false.
