AWS EMR Cluster Monitoring Dashboard
Question
A team is building an EMR Cluster in AWS.
The monitoring team has a requirement to ensure that they have a dashboard which can be used to monitor the entire cluster and also individual nodes.
Which of the following can be installed with the EMR Cluster to provide the monitoring dashboard?

A. B. C. D.Answer - D.
The AWS Documentation mentions the following.
The Ganglia open source project is a scalable, distributed system designed to monitor clusters and grids while minimizing the impact on their performance.
When you enable Ganglia on your cluster, you can generate reports and view the performance of the cluster as a whole, as well as inspect the performance of individual node instances.
Ganglia is also configured to ingest and visualize Hadoop and Spark metrics.
Option A is invalid because this tool is used to create and share documents that contain live code, equations, visualizations, and narrative text.
Option B is invalid because this tool is used as a workflow scheduler to manage and coordinate Hadoop jobs.
Option C is invalid because this tool is used for transferring data between Amazon S3, Hadoop, HDFS, and RDBMS databases.

https://docs.aws.amazon.com/emr/latest/ReleaseGuide/emr-ganglia.htmlThe correct answer is D. Ganglia.
Ganglia is a popular monitoring tool for clusters that is commonly used with Hadoop and other distributed computing systems. It is open-source software that allows you to view real-time metrics and graphs of cluster health, resource usage, and other important performance data. Ganglia is designed to be highly scalable and can monitor large clusters with thousands of nodes.
EMR (Elastic MapReduce) is Amazon's managed Hadoop service that allows you to easily process large amounts of data using a distributed computing framework. EMR supports a variety of Hadoop ecosystem tools, including Ganglia for cluster monitoring.
Jupyter Notebook, Oozie, and Sqoop are all tools that can be used with EMR for data processing and workflow management, but they are not monitoring tools.
Jupyter Notebook is an open-source web application that allows you to create and share documents that contain live code, equations, visualizations, and narrative text. It is commonly used for data exploration, data analysis, and machine learning.
Oozie is a workflow scheduler for Hadoop jobs. It allows you to define complex workflows that can include multiple Hadoop jobs and other actions, such as sending emails or running scripts.
Sqoop is a tool for importing and exporting data between Hadoop and relational databases. It allows you to easily move data between Hadoop and traditional data stores, such as MySQL, Oracle, and SQL Server.
In summary, while Jupyter Notebook, Oozie, and Sqoop are useful tools for data processing and workflow management, Ganglia is the correct answer for the question of which tool can be installed with EMR to provide cluster monitoring.
