Published on

Apache Storm is a free and open source, distributed real-time computation system for processing fast, large streams of data. Storm adds reliable real-time data processing capabilities to Apache Hadoop 2.x. Its effective stream processing capabilities are trusted by Twitter and Yahoo for quickly extracting insights from their Big Data.

  6. 6. What is Storm ?  Apache Storm is a free and open source distributed real-time computation system.  Storm makes it easy to reliably process unbounded streams of data.  Storm does for real-time processing what Hadoop did for batch processing.  Simple, can be used with any programming language. www.edureka.in/apache-stormTwitter @edurekaIN, Facebook /edurekaIN, use #askEdureka for Questions

  8. 8. ZooKeeper Nimbus ZooKeeper ZooKeeper Supervisor Supervisor Supervisor Supervisor Supervisor Nimbus node (master node, similar to the Hadoop JobTracker): » Uploads computations for execution » Distributes code across the cluster » Launches workers across the cluster » Monitors computation and reallocates workers as needed ZooKeeper nodes: » Coordinates the Storm cluster Supervisor nodes : » Communicates with Nimbus through Zookeeper, starts and stops workers according to signals from Nimbus Storm Components A Storm cluster has 3 sets of nodes 1. Nimbus node 2. Zookeeper nodes 3. Supervisor nodes www.edureka.in/apache-stormTwitter @edurekaIN, Facebook /edurekaIN, use #askEdureka for Questions
  9. 9. The work is delegated to different types of components that are each responsible for a simple specific processing task. The input stream of a Storm cluster is handled by a component called a spout. The spout passes the data to a component called a bolt, which transforms it in some way. A bolt either persists the data in some sort of storage, or passes it to some other bolt.

  10. 10. Why Storm is ideal for Real Time Processing Fast – benchmarked as processing one million, 100 byte messages, per second per node. Scalable – with parallel calculations that run across a cluster of machines. Fault-tolerant – when workers die, Storm will automatically restart them. If a node dies, the worker will be restarted on another node. Reliable – Storm guarantees that each unit of data (tuple) will be processed at least once or exactly once. Messages are only replayed when there are failures. Easy to operate – standard configurations are suitable for production on day one. Once deployed, Storm is easy to operate. http://hortonworks.com/hadoop/storm/ www.edureka.in/apache-stormTwitter @edurekaIN, Facebook /edurekaIN, use #askEdureka for Questions
