In this post, we will discuss different modes of Hadoop installation and their practical usage.
Modes of Hadoop Installation:
There are 3 modes of Hadoop installation:
HDFS and YARN are not applicable in this mode. Ideal to test MapReduce logic.
▶ Pseudo Distributed
It is Hadoop components on a single computer. HDFS, YARN and MapReduce can operate, but single machine constraints. Ideal to test out MapReduce logic and HDFS interactions.
▶ Fully Distributed
The real power of Hadoop shines through. It is a Multi Node distributed cluster.
How to experiment with Hadoop ?
➡ Pseudo Distributed Mode on a local machine using pre-configured Cloudera VMs.
➡ Using cloud services like GCP
