Can't get datastax-agent to run on a new node

  • 772

I'm trying to install the datastax-agent on a new CentOS node (there are 3 other nodes currently up and running correctly).

After installing the datastax-agent via the Opscenter UI it appears to install but still claims only 3 of 4 agents are connected.

The service is running on the new node, upon checking the agent.log I get these errors:

  1. Ah it was a silly little thing, for some reason the home directory for the user account needed to run the datastax-agent service had the wrong permissions. Easy enough to fix once I figured out what was wrong :)
