You want to sacrifice security for convenience: using a single principal and keytab for all nodes instead of unique principals for the nodes. If yes, I hope your customer specifically requested this insecure setup, or has been informed this misuse of kerberos will seriously degrade security. While I do not condone this setup, you should be able to append the junk service host "hadoop" to the line in /etc/hosts corresponding to the interface you want to use. Or make the DN listen on 0.0.0.0. > DN Reg can Fail when principal doesn't contain hostname and floatingIP is configured. > ------------------------------------------------------------------------------------- > > Key: HDFS-12532 > URL: https://issues.apache.org/jira/browse/HDFS-12532 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Brahma Reddy Battula > Assignee: Brahma Reddy Battula > Attachments: HDFS-12532.patch > > > Configure principal without hostname (i.e hdfs/hadoop@HADOOP.com) > Configure floatingIP > Start Cluster. > Here DN will fail to register as it can take IP which is not in "/etc/hosts". -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: hdfs-issues-help@hadoop.apache.org
