These are the components of a Hadoop cluster:

  1. Name node: Hold Meta Data
  2. Task Tracker: Accept tasks
  3. Job Tracker: Farms out Map reduce tasks
  4. Data Node: Holda Data
  5. Secondary Name node: Managed edit log of namenode. Don't let the name deceive you, its not a backup/failover.

In a single node mode: All components lie on a single machine

In a multi node mode: All components are distributed on several machines.

In a pseudo distributed mode: The components run on local machine which simulates a small cluster. HDFS is still used instead of the local filesystem
