FAILED: Error in metadata: javax.jdo.JDODataStoreException: Exception thrown performing schema
operation : Add classes to Catalog "", Schema "APP"

> Yes, I am guilty as charged, I don't use mac like the rest of you :)
> The Hive CLI currently doesn't work with cygwin under windows, this is due to the dual
path model that cygwin employs (there are file paths relative to the cygwin virtual root,
and file paths relative to the windows root)
> Since Sun's JDK is installed under the windows environment, if the paths are not converted
to windows format before being passed along then java will be at a loss to where the files
are. The solution is to use the cygpath command to convert the paths to windows format before
passing along to java world.
> I have a fix for this already, still doing some further testing (to make sure it works
under both unix and windows environments), then I will submit patch to this bug (should submit
before end of this week).
> Cheers,
