> I started with some test with the following code. But It seem I cannot
delete the directory.
@sokui The parentDir should be "a/b/" with trailing slash. Because there was
no trailing slash your key is "a/b<key_name>", so only "a/" parent directory is
created. Therefore, deleting "a/b" will return KEY_NOT_FOUND
I created the following test, you can adapt it to your test.
```java
@Test
public void testAbortMultipartUploadSuccessWithMissingParentDirectories()
throws Exception {
String parentDir = "parentDirToDelete/";
keyName = parentDir + UUID.randomUUID();
OzoneManager ozoneManager = cluster.getOzoneManager();
String buckKey = ozoneManager.getMetadataManager()
.getBucketKey(volume.getName(), bucket.getName());
OmBucketInfo buckInfo =
ozoneManager.getMetadataManager().getBucketTable().get(buckKey);
BucketLayout bucketLayout = buckInfo.getBucketLayout();
ozClient.getProxy().createDirectory(volumeName, bucketName, parentDir);
String uploadID = initiateMultipartUpload(bucket, keyName, RATIS,
ONE);
Pair<String, String> partNameAndETag = uploadPart(bucket, keyName,
uploadID,
1, "data".getBytes(UTF_8));
OMMetadataManager metadataMgr =
cluster.getOzoneManager().getMetadataManager();
String multipartKey = verifyUploadedPart(uploadID,
partNameAndETag.getKey(),
metadataMgr);
// Delete parent directory
ozClient.getProxy().deleteKey(volumeName, bucketName, parentDir, false);
// Abort multipart upload with missing parent directory
bucket.abortMultipartUpload(keyName, uploadID);
String multipartOpenKey =
metadataMgr.getMultipartKeyFSO(volumeName, bucketName, keyName,
uploadID);
OmKeyInfo omKeyInfo =
metadataMgr.getOpenKeyTable(bucketLayout).get(multipartOpenKey);
OmMultipartKeyInfo omMultipartKeyInfo =
metadataMgr.getMultipartInfoTable().get(multipartKey);
assertNull(omKeyInfo);
assertNull(omMultipartKeyInfo);
}
```
