I am installing Hadoop 2.7.3 on my Ubuntu 16.0.4 system. I am getting following error while trying to execute start-dfs.sh. I have checked all configuration files.

node@hellbot:~$ start-dfs.sh
17/01/28 20:46:26 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
Starting namenodes on [localhost]

Thanks in advance

  • According to the Logs problem is not with name node but it had something to do with your Hadoop library. Have you set the .bashrc file ? – siddhartha jain Jan 29 '17 at 08:31

    There is no errors, its only a warning which won't restrict namenode from starting. Please post the actual error log if any. – Devas Jan 29 '17 at 12:55
  • I agree with @Krishas, I've seen this warning before and our cluster didn't experience an actual fault because of it. – Fredulom Jan 30 '17 at 16:18
  • thanks for the suggestions and help...hadoop is working fine now even with that warning message. – Kumar-58 Jan 31 '17 at 19:30
