How do I tell what version of Cassandra I'm running?

I just spun up a machine on EC2 running Cassandra following the instructions in the link below, but I have no idea what version it is. How do I figure this out? I know I'm missing something incredibly simple, just don't know where to look.

You could query your package manager:

dpkg -l cassandra

or

yum info cassandra

May also use "SHOW VERSION" command in CQL:

cqlsh:mydb> SHOW VERSION ;
[cqlsh 5.0.1 | Cassandra 2.1.2 | CQL spec 3.2.0 | Native protocol v3]

You could use cqlsh.

$ cqlsh

Connected to Test Cluster at localhost:9160.
[cqlsh 3.1.8 | Cassandra 1.2.18 | CQL spec 3.0.5 | Thrift protocol 19.36.2]
Use HELP for help.

It might be easier to use nodetools

./nodetool -h localhost version

Try the describe_version() method.

After reviewing the instructions you listed, it looks like you're on a Debian(-based) system. In particular, in the "Cassandra Basic Setup" section, it says:

Step 3. Install the Debian package for Cassandra

% apt-get update % apt-get install cassandra

At this point, Cassandra will be installed and running. However, it's not configured for a multi-node cluster. So we need to continue.

If you followed this step to install Cassandra, you can simply use Debian's package management tool to inquire about the package you installed:

% dpkg -s cassandra
