> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Reporter: Sean Mackrory
> Assignee: Sean Mackrory

> There's a TODO in dirListingUnion:
> {quote}// TODO optimize for when allowAuthoritative = false{quote}
> There will be cases when we can intelligently avoid a round trip: if S3A
> results are a subset or the metadatastore results (including them being equal
> or empty) then writing back will do nothing (although perhaps that should set
> the authoritative flag if it isn't set already).
> There may also be cases where users want to just skip that altogether. It's
> wasted work if authoritative mode is disabled, so perhaps we want to trigger
> a skip if that's false, or perhaps it should be a separate property. First
> one makes for simpler config, second is more flexible...
