> Key: HADOOP-14766
> URL: https://issues.apache.org/jira/browse/HADOOP-14766
> Project: Hadoop Common
> Issue Type: New Feature
> Components: fs, fs/azure, fs/s3
> Affects Versions: 2.8.1
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Minor
> Attachments: HADOOP-14766-001.patch, HADOOP-14766-002.patch

>
> {{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.
