Yiqun Lin commented on HDDS-1120:
---------------------------------
Thanks for addressing the comment, [~bharatviswa]! Only one small suggestion:
Can we reuse common lines in two test case? I mean we can extract follow lines
to a method.
{code:java}
String volumeName = UUID.randomUUID().toString();
String bucketName = UUID.randomUUID().toString();
String value = "sample value";
store.createVolume(volumeName);
OzoneVolume volume = store.getVolume(volumeName);
volume.createBucket(bucketName);
OzoneBucket bucket = volume.getBucket(bucketName);
String keyName = UUID.randomUUID().toString();
// Write data into a key
OzoneOutputStream out = bucket.createKey(keyName,
value.getBytes().length, ReplicationType.RATIS,
ReplicationFactor.ONE, new HashMap<>());
out.write(value.getBytes());
out.close();
// We need to find the location of the chunk file corresponding to the
// data we just wrote.
OzoneKey key = bucket.getKey(keyName);
long containerID = ((OzoneKeyDetails) key).getOzoneKeyLocations().get(0)
.getContainerID();
// Get the container by traversing the datanodes. Atleast one of the
// datanode must have this container.
Container container = null;
...
Assert.assertNotNull("Container not found", container);

> Currently, if the checksum is computed during data write and persisted in the
> disk, we will always end up verifying it while reading. This Jira aims to
> selectively disable checksum verification during reads even though checksum
> info is present in the data stored.
