This is because after namenode is restarted, the still alive data node will try to register itself with the namenode and it identifies itself with its *IP address*. However, namenode only allows all the hosts in its hosts list to registrant and all of them are hostnames. So namenode would deny the datanode registration. -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira
