[jira] [Comment Edited] (HDFS-11779) Ozone: KSM: add listBuckets
[ https://issues.apache.org/jira/browse/HDFS-11779?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16024219#comment-16024219 ]

-------------------------------------------------------------
I studied amazone s3 a bit, according to s3 document [http://docs.aws.amazon.com/AWSJavaSDK/latest/javadoc/com/amazonaws/services/s3/AmazonS3Client.html#listBuckets--], the {{listBuckets}} API simply returns a list of buckets.
{code}
public List<Bucket> listBuckets() throws SdkClientException, AmazonServiceException
{code}
Do we really to support pagination for buckets? There won't be too many buckets in a volume, I propose to use similar signature as s3.
{code}
/**
* Returns a list of all buckets in the given volume.
*
* @param volumeName name of the volume.
* @return a list of buckets.
* @throws IOException
*/
public List<Bucket> listBuckets(String volumeName) throws IOException;
{code}
[~xyao], [~anu], does this make sense to you?
Thank you.
