[jira] [Created] (HADOOP-17492) abfs listLocatedStatus to support incremental/async page fetching

Steve Loughran created HADOOP-17492:
---------------------------------------

             Summary: abfs listLocatedStatus to support incremental/async page fetching
                 Key: HADOOP-17492
                 URL: https://issues.apache.org/jira/browse/HADOOP-17492
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/azure
    Affects Versions: 3.3.0
            Reporter: Steve Loughran


listLocatedStatus uses listStatus[] then serves up as an iterator.

Once HADOOP-17475 is in, it can do the list incrementally with async prefetch.

Although not used much in the Hadoop codebase, the LocationStatusFetcher class is used during query planning across applications
