How Cloudera Works and Architecture?

Cloudera’s architecture is based on Apache Hadoop’s distributed computing model. The key components are:

Hadoop Distributed File System (HDFS): It stores and manages the data across the cluster, providing fault tolerance and scalability.

YARN (Yet Another Resource Negotiator): YARN manages cluster resources and schedules jobs for processing.

Cloudera Manager: It provides a centralized management console to monitor and manage the entire cluster.

Cloudera Navigator: It offers data governance and management features, including data discovery, lineage, and metadata management.

Hive and Impala: These SQL query engines allow users to interact with data using familiar SQL commands.

Spark and Kudu: Spark is used for in-memory data processing, while Kudu provides fast analytics on streaming and historical data.

How to Install Cloudera

Installing Cloudera is a straightforward process. First, you’ll need to download the Cloudera Manager and Cloudera Distribution of Hadoop. Once you have these files, you can run the installation wizard, which will guide you through the process of setting up Cloudera on your system.
