Hadoop deployment modes

Hadoop supports three deployment modes, which are briefly (don't want to deviate too far from the crux of this chapter) detailed here:

• Standalone (Local) Mode
  • Default mode
  • Single Java (JVM) process
  • Non-distributed or non-clustered architecture
  • The easiest setup of the three
  • Mostly used for learning and running examples and for development
  • Very useful for debugging purposes
• Pseudo Distributed Mode (single node cluster)
  • Single-node installation
  • Each daemon runs in its own Java (JVM) process
  • Can be used for simulating multi-node installation/support issues in a single node itself (mini cluster setup on single node)
  • Much easier to setup than fully distributed Hadoop installation
  • Similar to the first mode, it is non-distributed ...
