I'm trying to build a new Cassandra cluster on Amazon EC2 using Opscenter for development use.
I have installed Opscenter (v4.1.3) on an EC2 instance using the instructions on http://www.datastax.com/documentation/opscenter/4.1/opsc/install/opscInstallRHEL_t.html, and followed the instructions in http://www.datastax.com/documentation/opscenter/4.1/opsc/online_help/opscCreatingCluster_t.html to build a two-node cluster. The node is not directly accessible from the public internet; I have configured an httpd rule on our NAT box to forward traffic to the opscenter install.
However, when I hit "Build Cluster" I get an error pop-up saying "Error checking provisioning requests: Unable to load /opscenter/request/[object Object]/status status: 404"
I've had a scan through the source as served by Opscenter, but it is all minified. I shall have a look through the source tarball tomorrow.
Any help gratefully received at this point.
