Anu Engineer commented on HDFS-11786:
-------------------------------------
[~msingh] Thanks for the initial patch. I would think that this change can be
done in copyFromLocal itself instead of introducing a new command.
We have to be careful that we don't change the semantics of existing arguments
and if new arguments are added they should not be required.
That will ensure that we don't break existing scripts.
> Add a new command for multi threaded Put/CopyFromLocal

> 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.
