Krishna Kumar Asawa commented on HDDS-8371:
-------------------------------------------
This looks Duplicate of https://issues.apache.org/jira/browse/HDDS-8292
> A keyName field in the keyTable might contain a full path for the key instead
> of the file name
> ----------------------------------------------------------------------------------------------
>
> Key: HDDS-8371
> URL: https://issues.apache.org/jira/browse/HDDS-8371
> Project: Apache Ozone
> Issue Type: Bug
> Components: OM
> Affects Versions: 1.3.0
> Reporter: Kohei Sugihara
> Priority: Major
>
> The listStatus API serves a repeated path in the list when a path for the key
> is deep. We noticed the listStatus API serves a corrupt result against some
> specific keys in a bucket. The corruption is that repeats a requested key
> prefix in a final list of the listStatus result like the following:
> {code:java}
> # expected case
> % aws s3 ls s3://bucket/a/b/c/d/e/f/g/file.zip
> <timestamp> <bytes> a/b/c/d/e/f/g/file.zip
> ...
> # actual: "a/b/c/d/e/f/g" is duplicated
> % aws s3 ls s3://bucket/a/b/c/d/e/f/g/file.zip
> <timestamp> <bytes> a/b/c/d/e/f/g/a/b/c/d/e/f/g/file.zip
> ... {code}
> Environment:
> * Ozone 1.3
> [compatible|https://github.com/apache/ozone/commit/9c61a8aa497ab96c014ad3bb7b1ee4f731ebfaf8]
> version (same environment as HDDS-7701, HDDS-7925)
> * Several large files, all of them are uploaded by multipart using AWS-CLI,
> divided into 8 MB chunks
> * An FSO-enabled bucket
> * OM HA
> Problem Details:
> I've dug the OM DB and found metadata in the keyTable has the full path for
> the key, so it finally appears redundant prefix twice in the result of the
> listStatus API.
> {code:java}
> # dump keyTable entries
> while (keyIter.hasNext()) {
> Table.KeyValue<String, OmKeyInfo> kv = keyIter.next();
> OmKeyInfo v = kv.getValue();
> LOG.info("v/b={}/{} parent={} Key={} size={} time={} checksum={} id={}
> keyName={}",
> kv.getValue().getVolumeName(), kv.getValue().getBucketName(),
> nodeId, kv.getValue().getFileName(),
> kv.getValue().getDataSize(), kv.getValue().getCreationTime(),
> kv.getValue().getFileChecksum(), kv.getValue().getObjectID(),
> kv.getValue().getKeyName());
