I had not set hadoop.security.group.mapping in my config. I was inheriting ShellBasedUnixGroupsMapping from core-default.xml.
I'm wondering if this is something a bit different. I only see the problem when running "hadoop fs -cat". I haven't seen it from any other command. For further testing, I did try setting JniBasedUnixGroupsMappingWithFallback in my config to see what would happen. When I do that, every command I run displays the warning. Switching back to ShellBasedUnixGroupsMapping, the warning only appears for "hadoop fs -cat" and no other commands.
