Cassandra

Installation

Requires Java8+ and Python
$ java -version
$ python --version

Option 1
$ pip install cql            # Installs CQL. To use cqlsh, the Cassandra query language shell.
$ brew install cassandra     # Installs Apache Cassandra

Verification

$ cassandra -v               # Prints the installed version

Managing Service

$ cassandra -f         # Starts Cassandra server using non-daemon process, allowing to see output in terminal
$ cqlsh                # If the server is up, run this command to open CQL shell

OR

$ launchctl load ~/Library/LaunchAgents/homebrew.mxcl.cassandra.plist        # Start Cassandra
$ launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.cassandra.plist      # Stop Cassandra

If any of these commands fail, execute the following once
$ cp /usr/local/Cellar/cassandra/<version number>/homebrew.mxcl.cassandra.plist ~/Library/LaunchAgents/
