[netCDFJava #LOO-265831]: Datatype conflict

Sorry, I was not clear. That .nc file that you have and already exists
was (it appears) written using the netcdf-3 format.
That is why you get the message
> java.lang.IllegalArgumentException: ucar.nc2.jni.netcdf.Nc4Iosp failed, 
> cannot use version netcdf4

You will need to write a new netcdf-4 file by:
1. creating it from scratch or
2. using the nccopy program to convert the existing netcdf-3 
   file to an equivalent netcdf-4 file.

Alternatively, of course, you can try writing the attribute as a 32 bit integer
rather than 64 bit, but that depends on what you are trying to do.
