Subject adding new node as tasktracker
Date Wed, 22 Jun 2011 14:39:42 GMT
just added a new node to our cluster like described here
http://wiki.apache.org/hadoop/FAQ#I_have_a_new_node_I_want_to_add_to_a_running_Hadoop_cluster.3B_how_do_I_start_services_on_just_one_node.3F

works just fine, except a minor flaw

on this site
http://jobtracker:50030/machines.jsp?type=active
all task trackers are listed, the first two columns are showing the url and the hostname of
the task trackers
our "old" mahines do have proper fally qualified host names, but the new one, for some reason,
has just the nacked IP address

why? how is the hostname of the new tasktracker calculated?

regards
andre
