Description
We have the following comment and implementation in DynamoDBMetadataStore:
// 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);
We have authoritative listings now in dynamo since HADOOP-15621, so we should resolve this comment, implement the solution and test it.
