Subject [jira] [Updated] (HADOOP-13974) S3a CLI to support list/purge of pending multipart commits
Date Wed, 13 Dec 2017 01:48:02 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-13974?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Aaron Fabbri updated HADOOP-13974:
----------------------------------
    Attachment: HADOOP-13974.005.patch

Posting v5 patch with feedback from [~stevel@apache.org].

- Clean up some imports / simplify boolean condition / fix indent.
- Create a single WriteOperationHelper when S3AFileSystem is created. Also, rename S3AFileSystem#createWriteOperationHelper()
to getWriteOperationHelper()
- Move listMultipartUploads() from S3ATestUtils to MultipartTestUtils
- Use explicit Charset for the input of "are you sure" prompt when aborting
  multipart uploads from CLI (for findbugs).
- ITestS3GuardToolLocal #uploadCommandAssertCount() prints output when it fails
  to match.

Tested in us-west 2.  Ran all integration tests and also verified CLI looks good in practice.

> 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
