2014-03-28 Thread Jon Forrest
In a previous message I described my guess at what was causing the Datastax Cassandra installation to require OpenJDK. Using the method I describe below, I'm now able to install the Datastax Cassandra rpm. Note that I have no idea (yet) whether Cassandra actually runs, but at least it installs. T

I've done a little more research on this problem. I'm now convinced that this is a Cassandra problem, but not the problem I had originally thought. For example, I downloaded cassandra12-1.2.15-1.noarch.rpm and I then ran the following with the results shown: # rpm -iv cassandra12-1.2.15-1.noarch
