--------------------------------
Summary: ScatterRackPolicy for Ratis container placement behaves
like RackAware policy
Key: HDDS-7265
URL: https://issues.apache.org/jira/browse/HDDS-7265
Project: Apache Ozone
Issue Type: Bug
Reporter: Neil Joshi
We expected container placement for ratis containers under the
SCMContainerPlacementRackScatter to behave as documented for EC. Instead, we
find when we configure ozone to use the SCMContainerPlacementRackScatter for
ratis container placement, the placement behaves like the
SCMContainerPlacementRackAware.
That is, for a cluster with 3 racks and Datanodes on each of the racks, with a
RATIS 3 configuration, to have pipelines and containers placed on each of the 3
racks. Instead we find that pipelines and containers are placed like
SCMContainerPlacementRackAware with 2 on one rack and 1 on another rack.
