A customer has a machine learning workflow that consist of multiple quick cycles of reads-writes-reads on Amazon S3. The customer needs to run the workflow on EMR but is concerned that the reads in subsequent cycles will miss new data critical to the machine learning from the prior cycles.

How should the customer accomplish this?

ATurn on EMRFS consistent view when configuring the EMR cluster

BUse AWS Data Pipeline to orchestrate the data processing cycles

CSet Hadoop.data.consistency = true in the core-site.xml file

DSet Hadoop.s3.consistency = true in the core-site.xml file

Option A - the 'turn it on and forget it' approach. Way better than option D, the 'make up config settings as you go' approach.

Hadoop.s3.consistency = true? That's a new one to me. I'd stick with the tried and true option A.

Setting Hadoop.data.consistency = true might work, but I'm not sure if that applies specifically to S3 data. Option A is probably safer.

AWS Data Pipeline could work, but that adds an extra layer of complexity. I'd go with the simpler option A.
