----------------------------------------
Hi [~brandonli],
Thanks for working on this.
I reviewed the patch and have one question, if user didn't specify old config
property "nfs.static.mapping.file" before, then the old default value
"/etc/nfs.map" was expected. Now with this change, even if user has
"/etc/nfs.map" file, user still need to rename /etc/nfs.map" to
"/ect/usergroupid.map". So it's kind of breaking backward compatibility. That
said, I don't see a good solution here to really maintain the full backward
compatibility. I just want to point this out. Comments? thanks.
