> DistCp to eliminate needless deletion of files under deleted directories
> ------------------------------------------------------------------------
>
> Key: HADOOP-15209
> URL: https://issues.apache.org/jira/browse/HADOOP-15209
> Project: Hadoop Common
> Issue Type: Improvement
> Components: tools/distcp
> Affects Versions: 2.9.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Priority: Major
> Attachments: HADOOP-15209-001.patch, HADOOP-15209-002.patch
>
>
> DistCP issues a delete(file) request even if is underneath an already deleted directory. This generates needless load on filesystems/object stores, and, if the store throttles delete, can dramatically slow down the delete operation.
> If the distcp delete operation can build a history of deleted directories, then it will know when it does not need to issue those deletes.
> Care is needed here to make sure that whatever structure is created does not overload the heap of the process.
