A county architect insists storage and resource management are separate Hadoop layers. Which statement correctly separates HDFS from YARN?
Select an answer to reveal the explanation.
Short Explanation
Storage shelves and a room-booking calendar are different tools. HDFS is the shelves for distributed files; YARN is the calendar that hands out CPU and memory. Collapsing them into one blurry service muddies county architecture reviews.
Full Explanation
HDFS is the distributed file system that stores blocks across DataNodes. YARN is the resource manager that allocates CPU and memory to applications. They cooperate but are distinct layers: storage versus compute scheduling. Treating YARN as the block store or merging them into one daemon misstates Hadoop’s design.
