Steve Loughran created MAPREDUCE-6760: -----------------------------------------
Summary: 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: mapreduce-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: mapreduce-issues-h...@hadoop.apache.org
