Background

To gain local access to the tools, utilities, and other resources on a cluster node associated with Oracle Big Data Cloud, you use Secure Shell (SSH) client software to establish a secure connection and log in as the user opc.

By default, network access to cluster nodes associated with Oracle Big Data Cloud is provided by Secure Shell (SSH) connections on port 22. Port 22 is the standard TCP/IP port that is assigned to SSH servers.

What Do You Need?

•  A running BDC instance
•  Putty ssh client for Windows.
• A client credentials zip file and its keystore password, that you defined in the previous tutorial or obtained from your Oracle Big Data Cloud administrator.
