I have a question. I’m currently taking a project to build data governance.
I have already connected master ip and slave1 ip to each other. Then, I have made ssh keys and copied.
I don’t think I have any errors about network.
Next, I tried to use hadoop as follow.
hdfs namenode -format
and I got a warning indicating
WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable
Although I got a warning sign, i don’t think it is a problem. However, I can’t get datanode after running start-dfs.sh and start-yarn even without any issue

Can someone tell me why I get this problem?
Hadoop configure I get is as below:
