Sean Mackrory commented on HADOOP-14505:
----------------------------------------
So the changes in HADOOP-13760 actually make a batch of mkdirs perform about
half as well as it used to. I've confirmed that this patch fixes it. It won't
apply cleanly to trunk right now just because it includes the new parameter to
makeDirsOrders added in HADOOP-14457, so we could easily reverse the order of
those 2 patches if we wanted.

> I noticed after reviewing the S3Guard delete tracking changes for
> HADOOP-13760, that mkdirs() can probably be simplified, replacing the use of
> checkPathForDirectory() with a simple getFileStatus().
> Creating a separate JIRA so these changes can be reviewed / tested in
> isolation.
