> Blocks of old key versions are not deleted on key deletion
> ----------------------------------------------------------

> Key: HDDS-6502
> URL: https://issues.apache.org/jira/browse/HDDS-6502
> Project: Apache Ozone
> Issue Type: Bug
> Reporter: Hanisha Koneru
> Assignee: Hanisha Koneru
> Priority: Major
> Labels: pull-request-available
>
> When a key is deleted from OM, only the latest version of blocks are sent to
> SCM for deletion.
> In _OmMetadataManagerImpl#getPendingDeletionKeys(),_ we gey the latest
> version location information and return only those blocks for deletion to
> {_}KeyDeletingService{_}. This leads to older versions of blocks being
> orphaned.
> {code:java}
> RepeatedOmKeyInfo infoList = kv.getValue();
> // Get block keys as a list.
> for (OmKeyInfo info : infoList.getOmKeyInfoList()) {
> OmKeyLocationInfoGroup latest = info.getLatestVersionLocations();
> List<BlockID> item = latest.getLocationList().stream()
> .map(b -> new BlockID(b.getContainerID(), b.getLocalID()))
> .collect(Collectors.toList());
> BlockGroup keyBlocks = BlockGroup.newBuilder()
> .setKeyName(kv.getKey())
> .addAllBlockIDs(item)
> .build();
> keyBlocksList.add(keyBlocks);
> currentCount++;
> }
