Rajesh Balamohan commented on HIVE-14953:
-----------------------------------------
[~sershe] - It should be listFiles(path, recursive). I accidentally added as
listStatus recursive in my earlier comment.
Default FS:
https://github.com/apache/hadoop/blob/branch-2.8/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/FileSystem.java#L1814
S3A FS which optimizes for bulk listing:
https://github.com/apache/hadoop/blob/branch-2.8/hadoop-tools/hadoop-aws/src/main/java/org/apache/hadoop/fs/s3a/S3AFileSystem.java#L2025
> don't use globStatus on S3 in MM tables

> Need to investigate if recursive get is faster. Also, normal listStatus might
> suffice because MM code handles directory structure in a more definite manner
> than old code; so it knows where the files of interest are to be found.
