> Key: HDDS-12071
> URL: https://issues.apache.org/jira/browse/HDDS-12071
> Project: Apache Ozone
> Issue Type: Bug
> Reporter: Sammi Chen
> Priority: Major
>
> For container schema V3, the metadata of a pending replicated container are
> dumped to *.data files under it's metadata/db/ directory. The *.data files
> will be packed into container tar package and sent to destination datanode.
> On the destination datanode, the tar package will be untared, and the *.data
> files will be read and loaded into data volume's rocksdb. After the container
> is imported successfully, the *.data files will be deleted on destination
> datanode container directory. While these files are still kept on the source
> datanode container directory. There is no harm of this behavior, for the
> next time, these *.data files will be deleted and new *.data files will be
> created if this container need be replicated again.
> This task aims to delete the *.data files on source datanode to release the
> disk space as soon as possible.
