Hadoop Mode

Hadoop can be configured in the following modes : -
  • Local Standalone Mode
  • Pseudo Distributed Mode
  • Fully Distributed Mode
Local Standalone Mode : – As the name suggest in the Local Standalone Mode user can configure and install hadoop and the local machine. Being a developer you can choose this mode to install hadoop and develope your map reduce programs and debug your application. 

Pseudo Distributed Mode : – In the Pseudo Distributed Mode we can configure the Hadoop on different different machine having their own separate JVM envioronment. 

Fully Distributed Mode : - This mode is quite similar to the Pseudo Distributed Mode with the exception instead of VM we will be using real Machine in the actual distributed environment. It is mostly used in the production deployment or environment.
