Final answer:
EMRFS Consistent View is a feature in EMR that ensures real-time file consistency across multiple clusters.
Step-by-step explanation:
EMRFS Consistent View is a feature in EMR (Elastic MapReduce) that enables real-time file consistency across multiple clusters. It ensures that different clusters using EMRFS (EMR File System) see the same version of a file at all times.
For example, if you have multiple EMR clusters running simultaneously and reading from or writing to the same files in an S3 bucket, EMRFS Consistent View guarantees that they will always see the most up-to-date version of the files. This is particularly important in scenarios where data consistency is crucial and real-time updates are being made to the files.
