If it takes you a long time to get home from work your session between your node1 and node2 could idle out and close.
Most firewalls will close down sessions that are idle too long for security measures. Use netstat command to verify that port 7777 is still up and listening for a connection coming only from our local loopback IP address. We now have an SSH tunnel created between our node1 and node2 and all that is left for us to do is to go home to our node2 and connect back to our node1, which would normally be blocked by corporate firewall. This option is useful if you just want to forward ports and not execute any commands on the remote host after you create your SSH tunnel. SSH version 2 introduced the “ -N” option which prevents execution of commands on the remote host. In this example, 10.0.0.11 is the IP address of the headnode that hosts the Livy service.You can add –v option for verbose debug mode.

A public gateway provides internet access to the following ports, which are common across all HDInsight cluster types. The nodes can't be directly accessed from the internet. Public portsĪll the nodes in an HDInsight cluster are located in an Azure Virtual Network. For more information, see Plan a virtual network for HDInsight. To join additional machines to the virtual network, you must create the virtual network first, and then specify it when creating your HDInsight cluster. However, you can't join other machines (such as other Azure Virtual Machines or your client development machine) to this virtual network. If you do not specify an Azure Virtual Network as a configuration option for HDInsight, one is created automatically.
