Is AWS S3 HDFS?

HDFS and the EMR File System (EMRFS), which uses Amazon S3, are both compatible with Amazon EMR, but they’re not interchangeable. HDFS is an implementation of the Hadoop FileSystem API, which models POSIX file system behavior.

Is HDFS faster than S3?

8xl (roughly 20MB/s per core). That is to say, on a per node basis, HDFS can yield 6X higher read throughput than S3. Thus, given that the S3 is 10x cheaper than HDFS, we find that S3 is almost 2x better compared to HDFS on performance per dollar.
