Steve Loughran updated HADOOP-15191: ------------------------------------ Status: Open (was: Patch Available) > Add Private/Unstable BulkDelete operations to supporting object stores for > DistCP > --------------------------------------------------------------------------------- > > Key: HADOOP-15191 > URL: https://issues.apache.org/jira/browse/HADOOP-15191 > Project: Hadoop Common > Issue Type: Sub-task > Components: fs/s3, tools/distcp > Affects Versions: 2.9.0 > Reporter: Steve Loughran > Assignee: Steve Loughran > Priority: Major > Attachments: HADOOP-15191-001.patch, HADOOP-15191-002.patch > > > Large scale DistCP with the -delete option doesn't finish in a viable time > because of the final CopyCommitter doing a 1 by 1 delete of all missing > files. This isn't randomized (the list is sorted), and it's throttled by AWS. > If bulk deletion of files was exposed as an API, distCP would do 1/1000 of > the REST calls, so not get throttled. > Proposed: add an initially private/unstable interface for stores, > {{BulkDelete}} which declares a page size and offers a > {{bulkDelete(List<Path>)}} operation for the bulk deletion. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
