I have created 2 node hadoop cluster, in which one one is windows machine (datanode) and another node is linux machine (namenode and datanode).

When I start cluster using start-dfs.sh from linux, it should start datanode on windows machine. but it is giving error hadoopslave01: Authentication failed.

hadoopslave01 is windows node.

how to fixed it. I am not using any authentication mechanism like kerberos.

  • Authentication using SSH might be failing – OneCricketeer Apr 25 '18 at 01:05
  • Yes but not getting why. I have ssh client on windows. I can ssh from windows to linux but vice versa not happening. I tried installing ssh server on windows but sshd service is not starting. – Vish Apr 26 '18 at 05:46
