If I were you, I would make sure all nodes were the same. The 32 / 64 thing might not be an issue, but you probably don't want that on a production cluster. What would help is if your pasted the output of all nodes for these commands:
1) echo $JAVA_HOME 2) echo $PATH 3) which java 4) java -version 5) whoami 6) ps aux | grep cassandra And if you could answer these questions: 1) how do you start Cassandra on the first 3 nodes? 2) how do you start it on the 4th node? 3) how did you start opscenter? I'm also a bit confused as to what your current problem is. Are you having trouble installing the opscener agents from the opscener ui? — Sent from Mailbox for iPhone On Thu, Apr 17, 2014 at 10:53 PM, Joyabrata Das <joy.luv.challen...@gmail.com> wrote: > Cool Buddy, I didn't email you directly because I didn't have it! > I didn't understand how it's polluting dev list as well? > 1.
