  This may happen if you use Cassandra embedded with Hawkular on *x systems
  
  Cassandra requres `ulimit` settings that are higher than usual on common *nix distributions. First check your present limits with `ulimit -a` and eventually increase open files to 65535 and max user processes to 4096 as appropriate on your system. 
  
  On RHEL, CentOS and Fedora the settings can be made persistent in `/etc/security/limits.conf` like this:

negative.code: single-node cluster. You do not have to worry about setting up and configuring
  Cassandra before getting started with Hawkular.
  
  For a more proper installation, please refer to link:installation.html[the installation guide]
  
  NOTE: The embedded Cassandra is not intended for production use, we definitely recommend to use a separate Cassandra server.
