Folks, I’d like to get REST gateway impersonation going on my cluster but I’m a little confused by the docs (section 55.8 of the reference guide for the version I’m using, 0.98.13.)
As I understand it (please let me know if I’m on the wrong track), this will let me send user credentials in on the REST call that match, say, the users in my HBase instance. These users have visibility labels associated with them and I assume that the labels will function normally with the credentials on the REST call. In any case, the 0.98.13 docs say that I should set ‘hadoop.proxyuser.$USER.groups’ to ‘$GROUPS’; same thing for ‘hadoop.proxyuser.$USER.hosts’. What’s the variable substitution for $USER and $GROUPS? Do I need to create these before I can use impersonation? Obviously I’m somewhat confused. Thanks for your help. -j
