Types of Hadoop Clusters

Question

I heard that there are different types of clusters like Single Node,Pseudo Distributed and MultiNode. Can anyone explain me the difference between the three types of cluster.

Answer 1

Below is the difference given between Standalone, Pseudo Distributed and Fully Distributed Mode:

Standalone mode – Default mode of Hadoop which utilize local file system for input and output operations instead of HDFS and is mainly used for debugging purpose

Pseudo Distributed mode (Single node cluster) – Hadoop cluster will be set up on a single server running all Hadoop daemons on one node and is mainly used for real code to test in HDFS.

Fully Distributed mode (Multi node cluster) – Setting up Hadoop cluster on more than one server enabling a distributed environment for storage and processing which is mainly used for production phase
