> 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.
