Hi all, I am trying to follow the instructions here for installing DSE 4.6 on AWS:
http://www.datastax.com/documentation/datastax_enterprise/4.6/datastax_enterprise/install/installAMIOpsc.html I was successful creating a single-node instance running OpsCenter, which I intended to bootstrap creating a larger cluster running Cassandra and Spark. During my first attempt, however, OpsCenter reported problems talking to agents in the new cluster I was creating. I ssh'ed into one of the new instances that I created with OpsCenter and saw that this was the problem: ------------------------------------ DataStax AMI for DataStax Enterprise and DataStax Community AMI version 2.4 ------------------------------------ DataStax AMI 2.5 released 02.25.2014 http://goo.gl/g1RRd7 This AMI (version 2.4) will be left available, but no longer updated. ------------------------------------ These notices occurred during the startup of this instance: [ERROR] 02/21/15-00:53:01 sudo chown -R cassandra:cassandra /mnt/cassandra: [WARN] Permissions not set correctly. Please run manually: [WARN] sudo chown -hR cassandra:cassandra /mnt/cassandra [WARN] sudo service dse restart It looks like by default, the OpsCenter GUI selects an out-of-date AMI (ami-4c32ba7c) when you click on "Create Cluster" and attempt to create a brand-new cluster on EC2. What is the recommended image to use here? I found a version 2.5.1 of the autoclustering AMI ( http://thecloudmarket.com/image/ami-ada2b6c4--datastax-auto-clustering-ami-2-5-1-hvm). Is that correct? Or should I be using one of the regular AMIs listed at http://www.datastax.com/documentation/datastax_enterprise/4.6/datastax_enterprise/install/installAMIOpsc.html ? Or just a standard ubuntu image? FWIW, I tried just using one of the AMIs listed on the DSE 4.6 page (ami-32f7c977), and I still see the "Waiting for the agent to start" message, although if I log in, things look like they have kind of worked: Cluster started with these options: None Raiding complete. Waiting for nodetool... The cluster is now in it's finalization phase. This should only take a moment...

I assume what I'm trying to do here is pretty common.
