I upgraded my cdh3u4 cluster to cdh4.1.3 recently and for the upgrade
i used cloudera manager cdh4.0.4. everything went fine until i wanted
to add hosts to assign roles to my cluster only to find that it doesnt
show any hosts on that page, its blank and did not assign any default
roles to any host. tried each and every thing, but the hosts dont show
up on that role assignment page. All the hosts in the hosts tab are
showing Good as well.
Any help will highly be appreciated
