Hadoop Operational Modes 

  • Local (Standalone) operation 
    • All Hadoop deamons (NameNode, DataNode, JobTracker, Task Tracker) are running on a single Java process (JVM) 
    • Uses local file system for storage 
  • Pseudo-distributed operation (test & development) 
    • Each Hadoop daemon runs in a separate Java process (JVM) but physically on a single machine 
  • Fully-distributed operation (production) 
    • Each Hadoop daemon runs on a different machine 
    • The power of Hadoop – parallel processing, scalability, automatic replication management, fault-tolerance, data consistency, workflow management – gets realized only in this mode
