Anu Engineer commented on HDFS-11786:
-------------------------------------
[~msingh] +1, great work. This is really a good change. One small nit: You
don't have to fix it, since it is a question of taste. I like my -args to be
single char or something that clearly explains the notion. "-nt" seems neither
here nor there. Would you please consider it renaming it to "t". Either way, I
am +1 on this change, pending jenkins.

> Project: Hadoop HDFS
> Issue Type: Bug

> CopyFromLocal/Put is not currently multithreaded.
> In case, where there are multiple files which need to be uploaded to the
> hdfs, a single thread reads the file and then copies the data to the cluster.
> This copy to hdfs can be made faster by uploading multiple files in parallel.
> I am attaching the initial patch so that I can get some initial feedback.
