Just a quick tip if you don’t like JConsole or you just prefer to have web UI for Cassandra’s JMX – there’s a quite ugly but usefull tool called MX4J and here’s how to make it work with Cassandra.
If you are a Cassandra user you’re probably experienced enough to know how to stop or restart Linux services – that’s an obvious thing. However in some cases it might be a problem if a service you turned off goes down, especially if other services have been using it. While Cassandra is very robust and crash-safe (
pkill -9 cassandra works fine ;-) ), it’s never a bad idea to do things in a way that minimizes the risk of something going wrong. The other advantage of clean Cassandra restart procedure is saving some startup time. Here is how to do it.
