Sahil Takiar commented on HADOOP-13600:
---------------------------------------
[[email protected]] thanks for taking a look!
* Thanks for the tip with the S3Guard testing, I re-ran the tests with the
local dynamodb enabled, tests pass
* I made some modifications so that all directories are deleted after the
files, and they are deleted in the order returned by
{{#listFilesAndEmptyDirectories}}
* I tried to move some stuff out into separate classes to decrease the # of
lines
* I creates a new class called `LazyTransferManager` that lazily initializes
the `TransferManager`
> S3a rename() to copy files in a directory in parallel

> Currently a directory rename does a one-by-one copy, making the request
> O(files * data). If the copy operations were launched in parallel, the
> duration of the copy may be reducable to the duration of the longest copy.
> For a directory with many files, this will be significant
