I am installing MapR 5.1.Converged Community Edition on a 3 Ubuntu 14.04 servers - Node 1, Node2, Node3. Downloaded setup script on Node 1 and it executed successfully with root user. Post that , MapR Web Installation is kicked off from Node 1 but is failing on Node2, Node3 during installation steps. Node verification step is successful for all nodes however actual installation step throws error for Node2, Node3 w.r.t. host not reachable and causing "/" mount having tmp and opt directories as read only mount leaving us with only option of rebooting the nodes. HTTP_PROXY and no_proxy settings are defined in environment file and even SSH connectivity is verified b/w nodes. Entries are also correct in hosts file. Web page says "Host unreachable" But the log says "Authentication failure" with /tmp directory
fatal: Authentication or permission failure. In some cases, you may have been able to authenticate and did not have permissions on the remote directory. Consider changing the remote temp path in ansible.cfg to a path rooted in "/tmp". Failed command was: mkdir -p $HOME/.ansible/tmp/ansible-tmp-1406841370.89-144706029120130 && chmod a+rx $HOME/.ansible/tmp/ansible-tmp-1406841370.89-144706029120130 && echo $HOME/.ansible/tmp/ansible-tmp-1406841370.89-144706029120130, exited with result 1:
Also, what username and Password should be there in "Configure Remote Authentication" - root user or mapr user or can be any user with sudo access?
Please help as I am stuck with installation. Many Thanks in advance.
