Attila Doroszlai commented on HDDS-2591: ---------------------------------------- Actually, the method is only used by tests. [~bharat], do you think it can be removed, or is there a plan to use it later? > No tailMap needed for startIndex 0 in ContainerSet#listContainer > ---------------------------------------------------------------- > > Key: HDDS-2591 > URL: https://issues.apache.org/jira/browse/HDDS-2591 > Project: Hadoop Distributed Data Store > Issue Type: Improvement > Components: Ozone Datanode > Reporter: Attila Doroszlai > Assignee: Attila Doroszlai > Priority: Minor > > {{ContainerSet#listContainer}} has this code: > {code:title=https://github.com/apache/hadoop-ozone/blob/3c334f6a7b344e0e5f52fec95071c369286cfdcb/hadoop-hdds/container-service/src/main/java/org/apache/hadoop/ozone/container/common/impl/ContainerSet.java#L198} > map = containerMap.tailMap(containerMap.firstKey(), true); > {code} > This is equivalent to: > {code} > map = containerMap; > {code} > since {{tailMap}} is a sub-map with all keys larger than or equal to > ({{inclusive=true}}) {{firstKey}}, which is the lowest key in the map.
