In the Hadoop ecosystem, Apache Zookeeper plays an important role in coordination amongst distributed resources. Apart from being an important component of Hadoop, it is also a very good concept to learn for a system design interview.
What is Apache Zookeeper?
Apache ZooKeeper is a coordination tool to let people build distributed systems easier. In very simple words, it is a central data store of key-value pairs, using which distributed systems can coordinate. Since it needs to be able to handle the load, Zookeeper itself runs on many machines.
Zookeeper provides a simple set of primitives and it is very easy to program.
It is used for:
- maintaining configuration
- failover management.
It does not suffer from Race Conditions and Dead Locks.Continue reading “How to Interact with Apache Zookeeper using Python?”
