There are two concerns here. Linux paths will work without adding
`file://`, and Windows will not. That might lead to confusion. Also, I doubt
that both Windows and Linux users typically add `file://` if they specify a
local path. As a rule of thumb, if no schema is given, then by default it is a
local path. The second concern is that `URI` requires percent encoded string,
so it does not work with white spaces or special symbols in the path. As far as
I understand, URI is for URIs and not for paths. If we want to use URI then we
need to change the variable name to `warehouseURI` and add a proper
documentation about this configuration parameter.
