Incorrect configuration: namenode address dfs.namenode.rpc-address is not configured

Question

I am getting this error when I try and boot up a DataNode. From what I have read, the RPC paramters are only used for a HA configuration, which I am not setting up (I think)

Answer 1

These steps solved the problem for me:

• export HADOOP_CONF_DIR = $HADOOP_HOME/etc/hadoop
• echo $HADOOP_CONF_DIR
• hdfs namenode -format
• hdfs getconf -namenodes
• ./start-dfs.sh
