Quick-Start Zookeeper for Fedora

This tutorial will guide you step-by-step on How to Getting-Started with Apache Zookeeper on Fedora GNU/Linux.

And ZooKeeper for Fedora allows distributed Processes to coordinate with each other through a shared hierarchal Namespace which is organized similarly to a standard File System.

The Name Space consists of Data Registers – called Znodes, in ZooKeeper parlance – and these are similar to Files & Directories.

Unlike a typical File System, which is designed for storage, ZooKeeper Data is kept In-memory, which means ZooKeeper can acheive High Throughput and Low Latency numbers.

Setting Up Zookeeper for Fedora

Zookeeper SetUp Fedora
Making the Zookeeper Data Directory
```
sudo su -c "mkdir /var/lib/zookeeper"
```
Creating the Zookeeper Configuration File
```
cd /opt/zookeeper
```
```
sudo su -c "nano conf/zoo.cfg"
```
Append for Example:
```
tickTime=2000
dataDir=/var/lib/zookeeper
clientPort=2181
```
tickTime: the basic time unit in milliseconds used by ZooKeeper. It is used to do heartbeats and the minimum session timeout will be twice the tickTime.
