After installing Hadoop when I am trying to start start-dfs.sh it is showing following error message. I have searched a lot and found that WARN is because I am using UBUNTU 64bit OS and Hadoop is compiled against 32bit. So its not an issue to work on. But the Incorrect configuration is something I am worried about. And also not able to start the primary and secondary namenodes. sameer@sameer-Compaq-610:~$ start-dfs.sh 15/07/27 07:47:41 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable Incorrect configuration: namenode address dfs.namenode.servicerpc-address or dfs.namenode.rpc-address is not configured.
