mac install kafka

1. brew install kafka

2. 

==> Pouring kafka-0.10.2.0.sierra.bottle.tar.gz

==> Caveats

To have launchd start kafka now and restart at login:

  brew services start kafka

Or, if you don't want/need a background service you can just run:

  zookeeper-server-start /usr/local/etc/kafka/zookeeper.properties & kafka-server-start /usr/local/etc/kafka/server.properties
