Anu Engineer commented on HDFS-11786:
-------------------------------------

[~boky01] This feature request case from a customer requirement. Hence we fixed it for a specific
case. We can certainly extend it.

> 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.
