Ambari vs Yarn: What are the differences?

Introduction

This Markdown code provides a comparison between Ambari and Yarn, highlighting their key differences.

Scalability and Performance: Ambari is a top-level Apache project that focuses on managing, monitoring, and provisioning Apache Hadoop clusters. It provides an intuitive web UI to manage various components of a cluster. On the other hand, Yarn (Yet Another Resource Negotiator) is a framework responsible for managing resources and scheduling applications in a Hadoop cluster. Yarn acts as the central resource manager and helps improve cluster utilization and performance by efficiently allocating resources to running applications.
Functionality: Ambari provides extensive functionality for managing Hadoop clusters, including installation, configuration, monitoring, and troubleshooting. It simplifies the management tasks by providing an easy-to-use interface. In contrast, Yarn is specifically designed to handle resource management and job scheduling in a Hadoop cluster. It focuses on efficiently allocating resources to different applications based on their requirements and priorities.
User Interface: Ambari offers a comprehensive web-based graphical user interface (GUI) that allows users to manage and monitor their Hadoop clusters. It provides a centralized management platform with a visual representation of the cluster components and their status. On the other hand, Yarn does not provide a dedicated user interface. It primarily operates through command-line utilities and APIs, which may require some scripting or custom development to interact with.
Integration: Ambari integrates well with various Hadoop components, including HDFS (Hadoop Distributed File System), Yarn, Hive, HBase, and others. It provides a unified management platform for these components, allowing users to configure and monitor multiple services from a single interface. Yarn, on the other hand, is tightly integrated with Hadoop and serves as the resource management framework for Hadoop clusters. It works seamlessly with other Hadoop components, such as HDFS and MapReduce.
Control and Customization: Ambari offers fine-grained control over cluster configuration and allows users to customize various aspects according to their specific requirements. It provides configuration wizards and templates for easy setup and management. In contrast, Yarn focuses more on resource management and scheduling rather than cluster configuration. It offers limited options for customization and configuration compared to Ambari.
Management Complexity: Ambari aims to simplify the management of Hadoop clusters by providing an intuitive interface and automation capabilities. It abstracts the underlying complexity of configuring and managing various Hadoop components, making it easier for administrators and operators. Yarn, on the other hand, is more focused on resource management and does not provide the same level of simplification for overall cluster management as Ambari.

In summary, Ambari is a comprehensive management platform for Hadoop clusters, offering extensive functionality, a user-friendly GUI, and customization options. On the other hand, Yarn is a resource management framework dedicated to efficiently allocating resources and scheduling applications in a Hadoop cluster.

Yarn

From a StackShare Community member: “I’m a freelance web developer (I mostly use Node.js) and for future projects I’m debating between npm or Yarn as my default package manager. I’m a minimalist so I hate installing software if I don’t need to- in this case that would be Yarn. For those who made the switch from npm to Yarn, what benefits have you noticed? For those who stuck with npm, are you happy you with it?"

Yarn

p.s.

I am not sure about the performance of the latest version of npm, whether it is different from my understanding of it below. Because I use npm very rarely when I had the following knowledge.

------⏬

I use Yarn because, first, yarn is the first tool to lock the version. Second, although npm also supports the lock version, when you use npm to lock the version, and then use package-lock.json on other systems, package-lock.json Will be modified. You understand what I mean, when you deploy projects based on Git...

Decided

As we have to build the application for many different TV platforms we want to split the application logic from the device/platform specific code. Previously we had different repositories and it was very hard to keep the development process when changes were done in multiple repositories, as we had to synchronize code reviews as well as merging and then updating the dependencies of projects. This issues would be even more critical when building the project from scratch what we did at Joyn. Therefor to keep all code in one place, at the same time keeping in separated in different modules we decided to give a try to monorepo. First we tried out lerna which was fine at the beginning, but later along the way we had issues with adding new dependencies which came out of the blue and were not easy to fix. Next round of evolution was yarn workspaces, we are still using it and are pretty happy with dev experience it provides. And one more advantage we got when switched to yarn workspaces that we also switched from npm to yarn what improved the state of the lock file a lot, because with npm package-lock file was updated every time you run npm install, frequent updates of package-lock file were causing very often merge conflicts. So right now we not just having faster dependencies installation time but also no conflicts coming from lock file.

What are some alternatives to Yarn, Ambari?

npm

npm is the command-line interface to the npm ecosystem. It is battle-tested, surprisingly flexible, and used by hundreds of thousands of JavaScript developers every day.

Grafana

Grafana is a general purpose dashboard and graph composer. It's focused on providing rich ways to visualize time series metrics, mainly though graphs but supports other ways to visualize data through a pluggable panel architecture. It currently has rich support for for Graphite, InfluxDB and OpenTSDB. But supports other data sources via plugins.

RequireJS

RequireJS loads plain JavaScript files as well as more defined modules. It is optimized for in-browser use, including in a Web Worker, but it can be used in other JavaScript environments, like Rhino and Node. It implements the Asynchronous Module API. Using a modular script loader like RequireJS will improve the speed and quality of your code.

Kibana
