             Summary: 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.
