Zookeeper uses Java. Either [Oracle Java](https://www.oracle.com/technetwork/java/javase/downloads/index.html) or [OpenJDK](https://openjdk.java.net/) will work.
## 2. Install Zookeeper
Install Zookeeper from [here](https://github.com/apache/zookeeper)
Install the tar.gz version by following the instructions on the github page
### 3. Install YCSB
Download the [latest YCSB](https://github.com/brianfrankcooper/YCSB/wiki/Getting-Started) file. Follow the instructions.
I recommend cloning the git repository and then building (since I have not tried downloading the tar.gz file). The command to do this is on the site:
At this point, the command line should have started. You can type "help" to see commands. Once you do that, you can open the terminal to zookeeper and see entries added. If you want to run any workloads, follow the [YCSB Site](https://github.com/brianfrankcooper/YCSB/wiki/Running-a-Workload)
