E. Configure SSH on the Unica Campaign listener server
This is the fifth step to integrate Unica Campaign with Hive-based Apache Hadoop data sources.
Before you begin
About this task
To enable data file transfers between the Unica Campaign listener (analytic) server and the Hive-based Hadoop big data instance, you must configure SCP and SSH seamless login. SSH allows secure connection between two computers; most systems use the OpenSSH client.
Procedure
-
On the machine that is running the Unica Campaign listener, configure SSH for no password prompt for authentication. Log in as the user who is
running the Unica Campaign listener and run the
following commands, substituting the username@IP address of your Hive server (in this
example, the MapR machine):
>> ssh-keygen -t rsa
>> ssh mapr@192.0.2.0 mkdir -p .ssh
>> cat .ssh/id_rsa.pub | ssh mapr@192.0.2.0 'cat >> .ssh/authorized_keys'
>> ssh mapr@192.0.2.0 "chmod 700 .ssh; chmod 640 .ssh/authorized_keys"
-
Verify password-less authentication using RSA-based authorized keys. Run each command,
substituting the actual username@IP address, and verify that it works. You need a local file
called test1 for this test to work:
>> ssh mapr@192.0.2.0
>> scp test1 mapr@192.0.2.0:/tmp
>> ssh mapr@192.0.2.0 "rm /tmp/test1"
