Incorrect configuration: namenode address DFS. namenode. servicerpc-address or DFS. namenode. RPC-address is not configured.

This error was reported when building a hadoop cluster.

Start HDFS to call the command:

Start-dfs.sh

Error:

 

Then, it is strange to lose the password. It is always unsuccessful.

 

 

Baidu for a long time, determined to be the problem of core-site.xml.

This Code determines what namenode rpcaddress:

<Property> <Name> fs. defaultfs </Name> <value> HDFS: // hdp-node-01: 9000 </value> </property>

However, I can't see any errors on the left or right. This hostname is also configured in hosts:

Hosts:

192.168.112.128 hdp-node-01

 

 

Finally, it may be a problem with the hadoop parsing configuration file. This configuration does not seem to allow spaces ??? (Excuse me ?)

At the beginning, I added a space in the value of <value> value </value> for ease of viewing, and removed the space at the end. The problem was solved ..............................
