I've installed DataStax OpsCenter (Apache Cassandra) and in OpsCenter, there is an error: "0 of 1 agents connected". When I click "fix", enter credentials and try to install nodes, i get error:

Unable to SSH to some of the hosts

Unable to SSH to 127.0.0.1: global name 'get_output' is not defined

Does anyone have any ideas how to fix it?

From the DataStax support forum: 0 of 1 agents connected : Unable to connect to Node. This probably belongs on another Stack Exchange site. - jww
This question appears to be off-topic because it is not about programming. See What topics can I ask about here in the Help Center. Perhaps Super User or Database Administrators Stack Exchange would be a better place to ask. - jww
Are you running opscenter on Windows? - arre
Yes, Windows 7 64 bit - mnowak

I fixed the problem with instruction from stackoverflow

The reason is OpsCenter could not find correct cassandra config file (cassandra.yaml).

In my case I installed cassandra to "D:\DataStax" instead of default location "C:\Program Files\DataStax Community". Add conf_location to opscenter\conf\clusters\local.conf solved my problem.

This is my final setting:

conf_location = [DataStax Install Dir]\apache-cassandra\conf\cassandra.yaml
