Which of the following services can feed data to the MapReduce jobs?
(Choose two.)
AWS DMS
Amazon Kinesis
AWS Data Pipeline
Amazon Athena
Amazon ES
Explanations:
AWS DMS (Database Migration Service) is primarily used for migrating databases to AWS. While it can replicate data continuously, it is not designed specifically to feed data to MapReduce jobs.
Amazon Kinesis is designed for real-time data streaming. It can ingest data continuously and feed it to various processing frameworks, including EMR for near-real-time data processing tasks.
AWS Data Pipeline is a web service that helps you process and move data between different AWS services. It can be used to schedule and automate data workflows, including feeding data to MapReduce jobs on Amazon EMR.
Amazon Athena is an interactive query service that allows you to analyze data in Amazon S3 using standard SQL. While it can query data, it does not directly feed data into MapReduce jobs; instead, it operates on the data already stored in S3.
Amazon Elasticsearch Service (Amazon ES) is designed for search and analytics, not specifically for feeding data into MapReduce jobs. While it can be used to analyze data, it does not facilitate the feeding of data to EMR for processing.
It seems to me that the answer is:
Amazon Kinesis
