Lokesh Jain commented on HDDS-1868: ----------------------------------- [~swagle] In the patch below condition would only be true for the leader datanode. {code:java} if (reply.getRoleInfoProto().hasLeaderInfo()) { reports.add(PipelineReport.newBuilder() .setPipelineID( PipelineID.valueOf(groupId.getUuid()).getProtobuf()) .build()); } {code} We would end up sending Pipeline Report only from leader to SCM. SCM should ideally receive pipeline reports from all datanodes in a pipeline in order to mark the pipeline as OPEN. The follower does get a roleInfoProto but reply.getRoleInfoProto().hasLeaderInfo() for a follower is false as it does not have leaderInfo but a followerInfo. > Ozone pipelines should be marked as ready only after the leader election is > complete > ------------------------------------------------------------------------------------ > > Key: HDDS-1868 > URL: https://issues.apache.org/jira/browse/HDDS-1868 > Project: Hadoop Distributed Data Store > Issue Type: Bug > Components: Ozone Datanode, SCM > Affects Versions: 0.4.0 > Reporter: Mukul Kumar Singh > Assignee: Siddharth Wagle > Priority: Major > Fix For: 0.5.0 > > Attachments: HDDS-1868.01.patch > > > Ozone pipeline on restart start in allocated state, they are moved into open > state after all the pipeline have reported to it.
