In my test environment, I used HDInsight Linux (Ubuntu) operating system for nodes within the Hadoop Cluster.
Command line for login Linux cluster:
<Cluster-Name>-ssh.azurehdinsight.net port 22 Primary head node
<Cluster-name>-ssh.azurehdinsight.net port 23 secondary headnode
<edgenodename>.<clustername>-ssh.azurehdinsight.net port 22 edge node
<cluster-name> -ed-ssh.azurehdinght.net port 22 (R server on HDInsight)
Step 1: If you don’t have PuTTY on your machine, download it from internet and install it before establish connection.
Step 2: Run your PuTTY software. Put the Hostname or IP Address and port number 22 for ssh connection.
Here my hostname is: “flightdelayh-ssh.azureinsight.net.”
If you don’t know hostname, go to the HDInsight Hadoop dashboard, overview configuration screen and “Secure Shell (SSH), and get your SSH hostname from there.
Step 3: After HDInsight Hadoop SSH connection hostname and port number. Click “Open” for establishing a connection.
Step 4: You will get the following message. Click “Yes” to connect.
Step 5: Provide SSH user name and password
Step 6: You can see the connection is established.
Thank you 🙂
