Shaik Idris Ali commented on HADOOP-13516:
------------------------------------------
HADOOP-11694 fixes only the case of empty root directory, however listing a
empty non-root directory still throws FileNonFoundException.
{code}
key = maybeAddTrailingSlash(key); //If this line is commented, then
objects.getCommonPrefixes().size is greater than 1 for valid empty directories.
with nextMarker like dir/empty-ids-1449644026143/
ListObjectsRequest request = new ListObjectsRequest();
request.setBucketName(bucket);
request.setPrefix(key);
request.setDelimiter("/");
request.setMaxKeys(1);
{code}
> Listing an empty s3a NON root directory throws FileNotFound.
