######################################################################## 100.0%
==> Pouring zookeeper-3.4.7.yosemite.bottle.tar.gz
==> Caveats
To have launchd start zookeeper at login:
ln -sfv /usr/local/opt/zookeeper/*.plist ~/Library/LaunchAgents
Then to load zookeeper now:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.zookeeper.plist
Or, if you don't want/need launchctl, you can just run:
zkServer start
==> Summary
/usr/local/Cellar/zookeeper/3.4.7: 235 files, 18M
