    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 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/
