Steve Loughran updated MAPREDUCE-6760:
--------------------------------------
    Target Version/s: 3.2.0  (was: 3.1.0)

> LocatedFileStatusFetcher to use listFiles(recursive)
> ----------------------------------------------------
>
>                 Key: MAPREDUCE-6760
>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6760
>             Project: Hadoop Map/Reduce
>          Issue Type: Improvement
>          Components: mrv2
>    Affects Versions: 2.8.0
>            Reporter: Steve Loughran
>            Priority: Major
>
> {{LocatedFileStatusFetcher}} does parallelized path listing, but it does make recursive calls on every subdir.
> If we could switch it to use {{FileSystem.listFiles(recursive)}}, object stores that have high-performance implementations of that operation would see significant speedup.
> HADOOP-13208 implements that for S3A; Azure, swift &c can do the same.
