Siddharth Wagle updated HDDS-3080:
----------------------------------
Parent Issue: HDDS-3722 (was: HDDS-698)
> Configurable container placement policy may not be compatible with pipeline
> placement policy
> --------------------------------------------------------------------------------------------
>
> Key: HDDS-3080
> URL: https://issues.apache.org/jira/browse/HDDS-3080
> Project: Hadoop Distributed Data Store
> Issue Type: Sub-task
> Components: SCM
> Affects Versions: 0.6.0
> Reporter: Stephen O'Donnell
> Priority: Major
>
> New pipelines are created on hosts in a rack aware way using
> PipelinePlacementPolicy, which supports only rack aware and random.
> However the Container Placement Policy used by ReplicationManager can be
> configured between the following using the config option
> ozone.scm.container.placement.impl:
> SCMContainerPlacementRackAware
> SCMContainerPlacementCapacity
> SCMContainerPlacementRandom
> If there is a network topology configured via net.topology.table.file.name,
> then it would be possible to have an incompatible setting for
> ozone.scm.container.placement.impl.
> We need to consider how to ensure the replication manager and Pipeline
> Provider always use compatible policies. One option may be to merge the rack
> aware policies as suggested in HDDS-3079, and also allow Capacity and Random
> to be used in the pipeline provider.
