Stephen O'Donnell commented on HADOOP-14698:
--------------------------------------------
I am +1 to commit this after a clean Yetus run. In the last run mvnsite is
failing for some reason. It may be a transient issue, so I have triggered it
again to see.
I also tested uploading about 2000 tiny files in a local docker environment -
running with "-t 4" was about twice as fast as no option. The -t option works
fine with put and copyFromLocal as expected with the patch.

> After HDFS-11786 copyFromLocal and put are no longer identical.
> I do not see any reason why not to add the new feature to put as well.
> Being non-identical makes the understanding/usage of command more complicated
> from user point of view.
