Subject Re: [VOTE] hadoop 0.23.6 rc1 release
Date Tue, 05 Feb 2013 21:19:03 GMT
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.

Thanks,
--Chris
