-----------------------------------------------
Resolution: Done
> Document change in debug replicas chunkinfo output
> --------------------------------------------------
>
> Key: HDDS-13339
> URL: https://issues.apache.org/jira/browse/HDDS-13339
> Project: Apache Ozone
> Issue Type: Bug
> Affects Versions: 2.0.0
> Reporter: Soumitra Sulav
> Assignee: Sarveksha Yeshavantha Raju
> Priority: Major
>
> Debug chunk info has a lot of changes in the JSON keys and format.
> This might break the existing parser/script and should be documented in the
> release docs.
> API has moved from
> {{ozone debug chunkinfo}} -> {{ozone debug replicas chunk-info}}
> JSON structure before:
> {code:java}
> {
> "KeyLocations" : [ [ {
> "Locations" : {
> "files" : [ "<block_path>" ],
> "pipelineID" : "<pipeline_id>"
> },
> "Datanode-HostName" : "<host_name>",
> "Datanode-IP" : "<host_ip>",
> "Container-ID" : <id>,
> "Block-ID" : <blockid>
> },{},{}
> ]]}
> {code}
> JSON structure now:
> {code:java}
> {
> "volumeName" : "<vol>",
> "bucketName" : "<buck>",
> "name" : "<key>",
> "keyLocations" : [ [ {
> "datanode" : {
> "hostname" : "<host_name>",
> "ip" : "<host_ip>",
> "uuid" : "<uuid>"
> },
> "file" : "<block_path>",
> "blockData" : {
> "blockID" : {
> "containerID" : <id>,
> "localID" : <localid>,
> "blockCommitSequenceId" : <bcsid>
> },
> "size" : <size>,
> "chunks" : [ {
> "offset" : <offset>,
> "len" : <len>,
> "checksums" : [ "<checksum>" ],
> "checksumType" : "<ctype>",
> "bytesPerChecksum" : <bpc>
> } ]
> }
> }, {}, {}
> ]]}
> {code}
>
> Key Differences
> |*Field*|*Old JSON*|*New JSON*|
> |Block
> path|data["KeyLocations"][0][0]["Locations"]["files"][0]|data["keyLocations"][0][0]["file"]|
> |Container ID|"Container-ID"|blockData.blockID.containerID|
> |Block ID|"Block-ID"|blockData.blockID.localID|
> |Hostname|"Datanode-HostName"|datanode.hostname|
