Question

Which component of the Hortonworks Data Platform (HDP) is the architectural center of Hadoop and provides resource management and a central platform for Hadoop applications?

A. HDFS
B. YARN
C. HBase
D. MapReduce

Answer 1

The architectural center of Hadoop and provides resource management and a central platform for Hadoop applications is YARN.

Step-by-step explanation:

The component of the Hortonworks Data Platform (HDP) that serves as the architectural center of Hadoop and provides resource management and a central platform for Hadoop applications is YARN (Option B).

YARN stands for Yet Another Resource Negotiator and is responsible for managing and allocating resources across the cluster. It separates the resource management and job scheduling/monitoring functions in Hadoop, allowing multiple applications to run simultaneously on the same cluster.

For example, YARN manages the resources for running MapReduce jobs and other distributed processing frameworks in Hadoop.

Answer 2

The component of the Hortonworks Data Platform (HDP) that serves as the architectural center of Hadoop, providing resource management and a central platform for Hadoop applications, is YARN. Option B is the answer.

Step-by-step explanation:

Hortonworks Data Platform (HDP) is an open-source distribution of Apache Hadoop, and YARN (Yet Another Resource Negotiator) is a key component within Hadoop's architecture. YARN serves as the resource management layer, allowing multiple applications to share resources on a Hadoop cluster. It acts as a central platform for Hadoop applications, enabling efficient and flexible resource allocation. HDFS (Hadoop Distributed File System) is the distributed file storage system, HBase is a NoSQL database, and MapReduce is a programming model for processing and generating large datasets. While these components are integral to Hadoop, YARN specifically handles resource management.

Option B is the answer.
