[jira] [Created] (HADOOP-17242) S3A (async) ObjectListingIterator to block in hasNext() for results

Steve Loughran created HADOOP-17242:
---------------------------------------

             Summary: S3A (async) ObjectListingIterator to block in hasNext() for results
                 Key: HADOOP-17242
                 URL: https://issues.apache.org/jira/browse/HADOOP-17242
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
    Affects Versions: 3.4.0
            Reporter: Steve Loughran
            Assignee: Steve Loughran


HADOOP-17074 made listing async in S3A, but the iterator's hasNext Call doesn't wait for the result. If invoked on an empty path it *may* return when it should be failing.

Note: surfaced in code review, not seen in the wild and all our tests were happy
