> Parallelize concatenation of distcp chunks of separate files in CopyCommitter
> -----------------------------------------------------------------------------
>
> Key: HADOOP-18739
> URL: https://issues.apache.org/jira/browse/HADOOP-18739
> Project: Hadoop Common
> Issue Type: Improvement
> Components: tools/distcp
> Reporter: Abhay Yadav
> Priority: Trivial
> Labels: pull-request-available
>
> While copying a folder containing large files consisting of multiple distcp
> chunks, copy committer synchronously picks chunks of each file and
> concatenates them. This part can be improved by parallelizing the
> concatenation of distcp chunks of separate files. We are able to save 2-3
> minutes while copying a folder of 100 GB containing 20 files of 5GB size with
> this improvement.
> Contributing a patch for this.
