Thanks Aditya, I have chosen public repository with ubuntu 14. In Install options: given host as "localhost" and then added ssh private key (ssh/id_rsa file) and then ssh username: root, ssh port: 22. But the cluster setup fails with message: ========================== Creating target directory... ========================== Command start time 2017-12-01 23:32:41 Permission denied (publickey,password).

Thanks Aditya... After changing to localhost as you suggested above it worked fine. Then I logged into ambari web cluster installation and trying to create user. Have few questions here: 1. At install Option as I am using my local laptop as a cluster can i give multiple hosts for namenode, snamenode, datanode1, datanode2 if yes hot do i need to give host names here? 2. In Host Registration Information: what SSH I need to give, how can i get this? 3. what i need to give near SSH user account and SSH port number? 4. After successful installation of hosts what will be the next steps i need to proceed? Thanks in Advance. ... View more
