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:

  • Looks like agent’s startup script can’t locate java binary correctly. I think I saw similar problems on centos before, and they were solved by setting JAVA_HOME env variable. Could you run /usr/share/datastax-agent/bin/find-java and post it’s output here? – arre Nov 03 '14 at 23:15
  • Thanks, you were correct I actually fixed that and just edited my question as there is a new bunch of errors (I didn't notice your reply to my original question until I had already edited it) – zoo_live_crew Nov 04 '14 at 00:27
  • And I did run the command you asked after I fixed it and I get: /usr/java/jdk1.7.0_45/bin/java – zoo_live_crew Nov 04 '14 at 00:28
  • I should also add that I did check the configuration file, and the permissions appear to be correct as they match the permissions of the config files on the nodes that are working correctly – zoo_live_crew Nov 04 '14 at 00:29

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 :)
