--------------------------------
As I look into this JIRA, I would like discuss some bout this JIRA:
1. the SCMHeartbeatRequestProto has included a list of PipelineReport
([https://github.com/apache/hadoop-ozone/blob/master/hadoop-hdds/container-service/src/main/proto/StorageContainerDatanodeProtocol.proto#L128])
2. HeartbeatEndpointTask is adding all pipeline reports into every heartbeat
request
([https://github.com/apache/hadoop-ozone/blob/master/hadoop-hdds/container-service/src/main/java/org/apache/hadoop/ozone/container/common/states/endpoint/HeartbeatEndpointTask.java#L182])
3. The XceiverServerRatis seems to handle all raft groups together and every
group has one pipelineId. Hence, every receiver server has all the pipeline
reports.
([https://github.com/apache/hadoop-ozone/blob/master/hadoop-hdds/container-service/src/main/java/org/apache/hadoop/ozone/container/common/transport/server/ratis/XceiverServerRatis.java#L599])
So it seems that currently heartbeat has considers a bulk of pipelineIds from
both sender and receiver sides. Do we have to make any changes to heartbeat
reports then?
And also, what's the benefit for us to only report open pipelines in reports?
