    Installing Cassandra on Mac OS X

Install Homebrew

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)"
Install Python

Mac OS X has a copy of Python preinstalled, but this makes sure you get the newest version.
brew install python
Install Pip

Pip is not usually installed by default
easy_install pip
Install cql

To use cqlsh, the Cassandra query language shell, you need to install cql:
pip install cql
Install Cassandra

This installs Apache Cassandra:
brew install cassandra
Starting/Stopping Cassandra

Use this command to start Cassandra:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.cassandra.plist
Use this command to stop Cassandra:
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.cassandra.plist
On Mavericks, Homebrew failed to move the plist file into LaunchAgents, which gives this error message:
launchctl: Couldn't stat("/Users/<user>/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/<version number>/homebrew.mxcl.cassandra.plist ~/Library/LaunchAgents/
