Lokesh Jain commented on HDDS-1448:
-----------------------------------
The changes required for this Jira would enable multiple three node pipelines
in a datanode. It was implemented this way to make sure that a datanode is not
part of more than one factor three pipeline.
> RatisPipelineProvider should only consider open pipeline while excluding dn
> for pipeline allocation

> Reporter: Mukul Kumar Singh
> Assignee: Aravindan Vijayan
> Priority: Major
> Labels: MiniOzoneChaosCluster

> While allocation pipelines, Ratis pipeline provider considers all the
> pipelines irrespective of the state of the pipeline. This can lead to case
> where all the datanodes are up but the pipelines are in closing state in SCM.
