Hello, how would you guys go about adding additional nodes to a Hadoop cluster running with Kerberos, preferably without restarting the namenode/resourcemanager/hbase-master etc?
I am aware that one can add names to dfs.hosts and run dfsadmin -refreshNodes, but with Kerberos I have the additional problem that the new hosts' principals have to be added to hadoop.security.auth_to_local (I do not have the luxury of an easy albeit secure pattern for host names). Alas, I see no way of propagating changes there to running demons. Any ideas? Thanks, Rainer
