Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password) during ambari hadoop installation
I encountered the same problem with him.
ssh -i <your_keypair> root@<your_host>I tried this but it wasn't solved.
Here's my solution
host1 ip:192.168.1.21
host2 ip:192.168.1.22
host3 ip:192.168.1.23
on host1:
rm -rf /root/.sshssh-keygen -t dsacat /root/.ssh/id_dsa.pub >> /root/.ssh/authorized_keysscp /root/.ssh/id_dsa.pub host2:/root/scp /root/.ssh/id_dsa.pub host3:/root/on host2:
rm -rf /root/.sshssh-keygen -t dsacat /root/id_dsa.pub >> /root/.ssh/authorized_keyson host3:
rm -rf /root/.sshssh-keygen -t dsacat /root/id_dsa.pub >> /root/.ssh/authorized_keyshost1:/root/.ssh/id_dsa This's the file which you need.
