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)}} operation for the bulk deletion. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: common-issues-help@hadoop.apache.org
