Yes. Writing objects from EMR Spark to S3 buckets in a different account. Immediately setting ACLs on the new objects fail as the objects are not yet “there”. Using EMRFS Consistent View was previously the obvious solution here, but it adds significant complexity.

EMRFS consistent view is a mess. Changes to S3 files are likely to break EMRFS, the metadata needs to be kept in sync (otherwise the table will keep increasing forever) with tools that are a pain to install, and when I used it to run Hive queries from a script, it didn't work.

This news is the death of EMRFS. The only thing it has left is fast listings of "directories" using DynamoDB.
