Ahhh! Very good. Should have known to try the simple solution first.
When trying this file with your recommendation but using v4.3, I'm
getting the following error:

Hi Kevin:
1) in general, use
java -Xmx512m -classpath netdfAll-<version>.jar ucar.nc2.dataset.NetcdfDataset
-in<fileIn> -out<fileOut> [-isLargeFile]
see:
http://www.unidata.ucar.edu/software/netcdf-java/reference/Cookbook.html#writeClasssic
2) it appears you are exceeding the 2G limit, so be sure to use
-isLargeFile flag
3) check to see if the variables are correct, since the tables may
need updating. Let me know if you see any problems

Greetings!
I have been using the utility ucar.nc2.iosp.grib.Grib2Netcdf in
toolsUI-4.1 successfully to convert High Resolution Rapid Refresh
(HRRR) GRIB2 files to netcdf-3.
When trying to use this utility in toolsUI-4.2, I am unable to
write out the file:

Unfortunately, I can't even find the Grib2Netcdf utility in
toolsUI-4.3.
Is this utility no longer available or supported? Is there
anything like it in 4.3? If not, is there a chance that I could
get this fixed in v4.2?
I'd be happy to supply the GRIB2 file if people want to test this.
Many thanks!!
