Check port 9000, maybe it is occupied by other programs, you can use sudo lsof -i :9000 to see the process occupying port 9000, as shown below, my port 9000 is occupied by clickhouse port 9000 Then modify the port in the core-site .xml, I modify it to 9001 here, restart, check the 9001 port, try to http://localhost:9870 again, and it succeeds. port 9001 port 9870

First, you need to check you Hadoop daemons are running by entering the command: jps. Here my namenode is also configured as datanode.

enter image description here

Second, check Namenode Java Process is running with 9870 port or not by entering the command.

netstat -an | grep 9870

Third, check dfs.namenode.http-address property in hdfs-site.xml

Finally, make sure you have disabled firewall
