Stephen O'Donnell updated HDDS-2446: ------------------------------------ Resolution: Won't Do Status: Resolved (was: Patch Available) Abandoning this Jira as we have decided on a different approach and this is no longer needed. > ContainerReplica should contain DatanodeInfo rather than DatanodeDetails > ------------------------------------------------------------------------ > > Key: HDDS-2446 > URL: https://issues.apache.org/jira/browse/HDDS-2446 > Project: Hadoop Distributed Data Store > Issue Type: Sub-task > Components: SCM > Affects Versions: 0.5.0 > Reporter: Stephen O'Donnell > Assignee: Stephen O'Donnell > Priority: Major > Labels: pull-request-available > Time Spent: 20m > Remaining Estimate: 0h > > The ContainerReplica object is used by the SCM to track containers reported > by the datanodes. The current fields stored in ContainerReplica are: > {code} > final private ContainerID containerID; > final private ContainerReplicaProto.State state; > final private DatanodeDetails datanodeDetails; > final private UUID placeOfBirth; > {code} > Now we have introduced decommission and maintenance mode, the replication > manager (and potentially other parts of the code) need to know the status of > the replica in terms of IN_SERVICE, DECOMMISSIONING, DECOMMISSIONED etc to > make replication decisions. > The DatanodeDetails object does not carry this information, however the > DatanodeInfo object extends DatanodeDetails and does carry the required > information. > As DatanodeInfo extends DatanodeDetails, any place which needs a > DatanodeDetails can accept a DatanodeInfo instead. > In this Jira I propose we change the DatanodeDetails stored in > ContainerReplica to DatanodeInfo. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
