Subject [jira] [Commented] (HADOOP-13974) S3a CLI to support list/purge of pending multipart commits
Date Wed, 01 Feb 2017 14:14:52 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13974?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15848410#comment-15848410
] 

Thomas Demoor commented on HADOOP-13974:
----------------------------------------

For purging we use TransferManagers abortMultipartUploads which under the hood does exactly
that: listMultipartuploads and then iterate that list and abort 1 by 1.

> The S3A CLI will need to be able to list and delete pending multipart commits. 
> We can do the cleanup already via fs.s3a properties. The CLI will let scripts stat for
outstanding data (have a different exit code) and permit batch jobs to explicitly trigger
cleanups.
> This will become critical with the multipart committer, as there's a significantly higher
likelihood of commits remaining outstanding.
> We may also want to be able to enumerate/cancel all pending commits in the FS tree
