Biju Nair updated HDFS-7810: ---------------------------- Description: When a new DN is added to the cluster, the registration process fails. The following are the steps followed. - Install and start a new DN - Add entry for the DN in the NN {{/etc/hosts}} file DN log shows that the registration process failed - Tried to restart DN with the same result Since all the DNs have multiple NW interface, we are using the following {{hdfs-site.xml}} property, instead of listing all the {{dfs.datanode.xx.address}} properties. {code:xml} <property> <name>dfs.datanode.dns.interface</name> <value>eth2</value> </property> {code} - Restarting the NN resolves the issue with registration which is not desired. - Adding the {{dfs.datanode.xx.address}} properties seem to resolve DN registration process without NN restart. But this is a different behavior compared to *hadoop 2.2*. Is there a reason for the change? was: When a new DN is added to the cluster, the registration process fails.
