---------------------------------------

             Summary: Hadoop: secondary file system is initialized on client even if there
are no explicit PROXY paths.
                 Key: IGNITE-2258
                 URL: https://issues.apache.org/jira/browse/IGNITE-2258
             Project: Ignite
          Issue Type: Bug
          Components: hadoop
    Affects Versions: ignite-1.4
            Reporter: Vladimir Ozerov
            Priority: Critical
             Fix For: 1.6


*Problem*:
In case at least one PROXY path exists, we intialize secondary file system on the client (IgniteHadoopFileSystem).

We have 4 "default paths" which are always defined (see IgfsImpl) and one of these paths is
in PROXY mode.
As a result, whenever secondary file system is defined, it will always be intiialized on the
client whether it is needed or not.

*Proposed solutions*:
a) Remove these default paths as they are of little use in real apps.
b) Or make them optional through configuration parameter.
