[jira] [Updated] (MAPREDUCE-6760) LocatedFileStatusFetcher to use
listFiles(recursive)
[ https://issues.apache.org/jira/browse/MAPREDUCE-6760?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Steve Loughran updated MAPREDUCE-6760:
--------------------------------------
Target Version/s: 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
>
> {{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.
