Sahil Takiar commented on HADOOP-13600: --------------------------------------- [~ste...@apache.org] thanks for taking a look! * Thanks for the tip with the S3Guard testing, I re-ran the tests with the local dynamodb enabled, tests pass * I made some modifications so that all directories are deleted after the files, and they are deleted in the order returned by {{#listFilesAndEmptyDirectories}} * I tried to move some stuff out into separate classes to decrease the # of lines * I creates a new class called `LazyTransferManager` that lazily initializes the `TransferManager` > S3a rename() to copy files in a directory in parallel > ----------------------------------------------------- > > Key: HADOOP-13600 > URL: https://issues.apache.org/jira/browse/HADOOP-13600 > Project: Hadoop Common > Issue Type: Sub-task > Components: fs/s3 > Affects Versions: 2.7.3 > Reporter: Steve Loughran > Assignee: Sahil Takiar > Attachments: HADOOP-13600.001.patch > > > Currently a directory rename does a one-by-one copy, making the request > O(files * data). If the copy operations were launched in parallel, the > duration of the copy may be reducable to the duration of the longest copy. > For a directory with many files, this will be significant -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
