Question

I’m trying to install and configure cassandra programmatically using a shell script.
I install cassandra, run ./cassandra and then I try to load the schema using cassandra-cli --host localhost -f <schema-file>. The problem is that it tries to load the schema before cassandra is up and throws an exception. Is there any way to know when cassandra is up and running?

Thanks!

You can check to see if anything is listening on 9160 (the Thrift port) prior to loading the schema. Binding to the port is the last thing the service does, and indicates it’s ready to service requests.

If Cassandra is running this command will return something:

sudo lsof -i :9160
