> S3Guard: S3AFileSystem::rename() should move non-listed sub-directory entries
> in metadata store
> -----------------------------------------------------------------------------------------------
>
> Key: HADOOP-14236
> URL: https://issues.apache.org/jira/browse/HADOOP-14236
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Reporter: Mingliang Liu
> Assignee: Mingliang Liu
> Priority: Critical
> Attachments: HADOOP-14236-HADOOP-13345.000.patch
>
>
> After running integration test {{ITestS3AFileSystemContract}}, I found the
> following items are not cleaned up in DynamoDB:
> {code}
> parent=/mliu-s3guard/user/mliu/s3afilesystemcontract/testRenameDirectoryAsExisting/dir,
> child=subdir
> parent=/mliu-s3guard/user/mliu/s3afilesystemcontract/testRenameDirectoryAsExistingNew/newdir/subdir,
> child=file2
> {code}
> At first I thought it’s similar to [HADOOP-14226] or [HADOOP-14227], and we
> need to be careful when cleaning up test data.
> Then I found it’s a bug(?) in the code of integrating S3Guard with
> S3AFileSystem: for rename we miss sub-directory items to put (dest) and
> delete (src). The reason is that in S3A, we delete those fake directory
> objects if they are not necessary, e.g. non-empty. So when we list the
> objects to rename, the object summaries will only return _file_ objects. This
> has two consequences after rename:
> # there will be left items for src path in metadata store - left-overs will
> confuse {{get(Path)}} which should return null
> # we are not persisting the whole subtree for dest path to metadata store -
> this will break the DynamoDBMetadataStore invariant: _if a path exists, all
> its ancestors will also exist in the table_.
> Existing tests are not complaining about this though. If this is a real bug,
> let’s address it here.
