Here is the error Log I'm seeing on my screen when I execute start-dfs.sh file by changing into Hadoop installed location:

(base) ramc@Rams-MBP ~ % start-dfs.sh

Starting namenodes on [Rams-MBP.attlocal.net] Rams-MBP.attlocal.net: WARNING: /opt/homebrew/Cellar/hadoop/3.3.4/libexec/logs does not exist.

Creating. Starting datanodes

2023-06-01 11:47:52,074 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

I've tried starting hadoop manually and also using start-dfs command but nothing works. I set Export and path in .bash_profile sucessfully.

  • Those are warnings, not errors. They should not prevent the execution. – aled Jun 01 '23 at 16:55
  • Ohhh Yeah, those are warnings. My bad ! But still I'm unable to go to next step. I'm executing "hdfs dfs -mkdir /data" command on my mac terminal. But it's giving me the warning "2023-06-01 12:15:20,090 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable mkdir: `/data': Input/output error" instead of creating the directory. – Ramc_26 Jun 01 '23 at 17:22
