Click on the arrows to vote for the correct answer
A. B. C. D.Answer : A.
Option A is correct -Hue (Hadoop User Experience) is an open-source, web-based, graphical user interface for use with Amazon EMR and Apache Hadoop.
Hue groups together several different Hadoop ecosystem projects into a configurable interface.
Amazon EMR has also added customizations specific to Hue in Amazon EMR.
Hue acts as a front-end for applications that run on your cluster, allowing you to interact with applications using an interface that may be more familiar or user-friendly.
The applications in Hue, such as the Hive and Pig editors, replace the need to log in to the cluster to run scripts interactively using each application's respective shell.
https://docs.aws.amazon.com/emr/latest/ReleaseGuide/emr-hue.htmlOption B is incorrect -Apache Flink is a streaming dataflow engine that you can use to run real-time stream processing on high-throughput data sources.
Flink supports event time semantics for out-of-order events, exactly-once semantics, backpressure control, and APIs optimized for writing both streaming and batch applications.
https://docs.aws.amazon.com/emr/latest/ReleaseGuide/emr-flink.htmlOption C is incorrect -Apache Phoenix is used for OLTP and operational analytics, allowing you to use standard SQL queries and JDBC APIs to work with an Apache HBase backing store.
https://docs.aws.amazon.com/emr/latest/ReleaseGuide/emr-phoenix.htmlOption D is incorrect -Apache Tez is a framework for creating a complex directed acyclic graph (DAG) of tasks for processing data.
In some cases, it is used as an alternative to Hadoop MapReduce.
https://docs.aws.amazon.com/emr/latest/ReleaseGuide/emr-tez.htmlThe EMR cluster launched by Allianz Financial Services (AFS) is meant to support their big data analytics requirements. AFS has a large team of Hadoop developers who work on both Hive and Pig applications. They are looking for a graphical user interface for use with Amazon EMR and Apache Hadoop that can group together several different Hadoop ecosystem projects into a configurable interface.
Among the given options, Apache Hue is the most suitable choice for AFS.
Apache Hue is a web-based graphical user interface that provides an easy-to-use, self-service portal for Apache Hadoop clusters. It allows users to interact with Hadoop services such as HDFS, Hive, Pig, Impala, and others through a single interface. Hue simplifies Hadoop application development by providing a web-based platform for accessing Hadoop services, creating and executing Hadoop jobs, and viewing the results.
Hue supports both Hive and Pig applications, which is essential for AFS as their Hadoop developers work on both. Moreover, Hue also offers configurable dashboards, a customizable home page, and the ability to create custom workflows, which would allow AFS to group together several different Hadoop ecosystem projects into a single interface.
Apache Flink is a distributed processing engine that can be used for batch and stream processing. It is not a graphical user interface and does not provide the required features to fulfill AFS's requirements.
Apache Phoenix is a relational database layer on top of Apache HBase, and it is not a graphical user interface. It does not provide the necessary features to fulfill AFS's requirements.
Apache Tez is a data processing framework that allows for high-performance and low-latency batch and interactive processing of data. However, it is not a graphical user interface and does not offer the necessary features to fulfill AFS's requirements.
Therefore, the best option for AFS is Apache Hue, which is a web-based graphical user interface that provides the required features to fulfill their requirements.
