I am following this official site and I am sure I am doing all right. However, I cannot run sbin/start-dfs.sh for a Pseudo-Distributed node. Everytime I am getting the following error:
starting namenodes on [localhost]
pdsh@ML-Learning: localhost:connect: Connection refused
starting datanodes
pdsh@ML-Learning: localhost:connect: Connection refused
starting secondary namenodes [ML-Learning]
pdsh@ML-Learning: localhost:connect: Connection refused
I executed ssh locaohost without password.
Previously, I was able to run the following commands to start namenode and datanode.
bin/hadoop --daemon start namenode
bin/hadoop --daemon start datanode
However, I cannot stop them with the following commands, and the error is saying those daemons are running with process
bin/hadoop --daemon stop namenode
bin/hadoop --daemon stop datanode
So I was simply killing those processes, and it seems after that I ruined my whole set up. I cannot start namenode and datanode anymore.
bin/hadoop --daemon start namenode
bin/hadoop --daemon start datanode
It stuck in the following message:
INFO blockmanagement.CacheReplicationMonitor: Starting CacheReplicationMonitor with interval 30000 milliseconds.
Any idea on this issue? I even restarted my VM, but the issue is still there.
