  • HDFS: A distributed file system that provides high throughput access to application data.
  • Hive: A data warehouse infrastructure that provides data summarization and ad hoc querying.
  • MapReduce: A software framework for distributed processing of large data sets on compute clusters.

  • ZooKeeper: A high-performance coordination service for distributed applications.
