Introduction to MRS Manager

Overview

MRS manages and analyzes massive data and helps you rapidly obtain desired data from structured and unstructured data. The structure of open-source components is complex. The installation, configuration, and management processes are time- and labor-consuming. MRS Manager is a unified enterprise-level cluster management platform and provides the following functions:

  • Cluster monitoring enables you to quickly view the health status of hosts and services.
  • Graphical metric monitoring and customization enable you to quickly obtain key information about the system.
  • Service property configurations can meet service performance requirements.
  • With cluster, service, and role instance functions, you can start or stop services and clusters in one click.

Introduction to the MRS Manager GUI

MRS Manager provides a unified cluster management platform, facilitating rapid and easy O&M for clusters. For details about how to access MRS Manager, see Accessing MRS Manager (MRS 2.x or Earlier).

Reference

MapReduce Service (MRS) is a data analysis service on the public cloud. It is used to manage and analyze massive sets of data.

MRS uses MRS Manager to manage big data components, such as components in the Hadoop ecosystem. Therefore, some concepts on the MRS Console on the public cloud must be different from those on MRS Manager. For details, see Table 3.
