Xiaoyu Yao commented on HDDS-324:
---------------------------------
Thanks [~msingh] for working on this. The latest patch look good to me. Just
have few minor comments:
*Pom.xml*
Can you elaborate on the change for upgrade ratis? Does the new version support
ReplicationLevel.*_ALL?_*
*PipelineID.java*
Line66: NIT: "pid" is confusing, can we change it to "pipelineId"
*Pipeline.java*
Line 250: NIT: "name:" -> "id:"
*XceiverServerRatis.java*
Line 298: can we make this a configurable option for choosing different
ReplicationLevel, such as ALL, MAJOR?
Line 308: this is a very good fix so that we don't use a random client id for
each request.
*ContainerInfo.java*
Line 240: NIT: pipelineName => pipelineID
*RatisManagerImpl.java*
Line 90: NIT: "name" -> "id"
*StandaloneManagerImpl.java*
Line 89: NIT: "name" -> "id"
*TestCloseContainerhandler.Java*
Line 23: unused imports
> Use pipeline name as Ratis groupID to allow datanode to report pipeline info

> Issue Type: Bug
> Components: Ozone Datanode
> Affects Versions: 0.2.1
> Reporter: Mukul Kumar Singh
> Assignee: Mukul Kumar Singh
> Priority: Major
> Fix For: 0.2.1

>
> Currently Ozone creates a random pipeline id for every pipeline where a
> pipeline consist of 3 nodes in a ratis ring. Ratis on the other hand uses the
> notion of RaftGroupID which is a unique id for the nodes in a ratis ring.
> When a datanode sends information to SCM, the pipeline for the node is
> currently identified using dn2PipelineMap. With correct use of RaftGroupID,
> we can eliminate the use of dn2PipelineMap.
