> *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.
