> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.1.0
> Reporter: Gabor Bota
> Assignee: Gabor Bota
> Priority: Major
> Fix For: 3.3.0

>
> We have the following comment and implementation in DynamoDBMetadataStore:
> {noformat}
> // When this class has support for authoritative
> // (fully-cached) directory listings, we may also be able to answer
> // TRUE here. Until then, we don't know if we have full listing or
> // not, thus the UNKNOWN here:
> meta.setIsEmptyDirectory(
> hasChildren ? Tristate.FALSE : Tristate.UNKNOWN);
> {noformat}
> We have authoritative listings now in dynamo since HADOOP-15621, so we should
> resolve this comment, implement the solution and test it.
