bharatviswa504 commented on issue #29: HDDS-2034. Async RATIS pipeline creation and destroy through heartbeat commands URL: https://github.com/apache/hadoop-ozone/pull/29#issuecomment-555667222 Hi @swagle Considering 1 node pipeline in HealthyPipelineSafeMode Rule will cause the issue. Example Scenario: If we consider both 3, and 1 node pipelines, then also we shall be in problem. The scenario is in a cluster it has 10 3 node pipelines in the cluster, and now if we consider both 3 and 1 to increment currentHealthyPipelineCount, there can be a case, when from each pipeline one Datanode is reported, and we increment the currentHealthyPipelineCount, and we might reach the threshold. But after coming out of safeMode there will be no 3 pipeline nodes in the cluster and writes will fail.
