Homebrew is a great little package manager for OS X. If you haven't already, installing it is pretty easy:
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
Mac OS X has a copy of Python preinstalled, but this makes sure you get the newest version.
brew install python
To use cqlsh, the Cassandra query language shell, you need to install cql:
pip install cql
pip install cassandra-driver
This installs Apache Cassandra:
brew install cassandra
At the end of the install, brew will tell you about two ways to launch Cassandra. The first will launch it when the computer restarts, but this isn't recommended because you may not want to always run Cassandra. Instead use this command:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.cassandra.plist
Or even easier:
launchctl start homebrew.mxcl.cassandra
and to stop:
launchctl stop homebrew.mxcl.cassandra
On Mavericks, Homebrew failed to move the plist file into LaunchAgents. Which gives this error message:
launchctl: Couldn't stat("/Users/MNCH/Library/LaunchAgents/homebrew.mxcl.cassandra.plist"): No such file or directory
To fix this just issue the following command. Then, try using the launchctl load command again:
cp /usr/local/Cellar/cassandra/2.1.2/homebrew.mxcl.cassandra.plist ~/Library/LaunchAgents/
Properties: /usr/local/etc/cassandra
Logs: /usr/local/var/log/cassandra
Data: /usr/local/var/lib/cassandra/data
$> cqlsh

Have fun with Cassandra!
I had the same problem. It doesn't necessarily has to be Java 9. I was using JDK 8u161 and the outcome was same.
Connection error: ('Unable to connect to any servers', {'127.0.0.1': error(61, "Tried connecting to [('127.0.0.1', 9042)]. Last error: Connection refused")})
I've found an error in logs of Cassandra, java.lang.AbstractMethodError. When I used older version JDK 8u152, it started to work. I've have a great post on stack overflow to install it via brew :)
