> {{hdfs put local s3a://path}} is suboptimal as it treewalks down down the source tree
then, sequentially, copies up the file through copying the file (opened as a stream) contents
to a buffer, writes that to the dest file, repeats.
> For S3A that hurts because
> * it;s doing the upload inefficiently: the file can be uploaded just by handling the
pathname to the AWS xter manager
> * it is doing it sequentially, when some parallelised upload would work. 
> * as the ordering of the files to upload is a recursive treewalk, it doesn't spread the
upload across multiple shards. 
> Better:
> * build the list of files to upload
> * upload in parallel, picking entries from the list at random and spreading across a
pool of uploaders
> * upload straight from local file (copyFromLocalFile()
> * track IO load (files created/second) to estimate risk of throttling.
