Summary: Add CLI Commands and Protobuf messages to trigger decom states Key: HDDS-2196 URL: https://issues.apache.org/jira/browse/HDDS-2196 Project: Hadoop Distributed Data Store Issue Type: Sub-task Components: SCM, SCM Client Affects Versions: 0.5.0 Reporter: Stephen O'Donnell Assignee: Stephen O'Donnell To all nodes to be decommissioned, recommissioned and put into maintenance, we need a few commands. These will be added to the existing "scm cli". 3 commands are proposed: Decommission: ozone scmcli dnadmin decommission hosta hostb hostc:port ... Put nodes into maintenance: osone scmcli dnadmin maintenance hosta hostb hostc:port ... <-endHours> Take nodes out of maintenance or halt decommission: ozone scmcli dnadmin recommission hosta hostb hostc:port These 3 commands will call 3 new protobuf messages and they will be part of the "StorageContainerLocationProtocol": * DecommissionNodesRequestProto * RecommissionNodesRequestProto * StartMaintenanceNodesRequestProto In additional a new class NodeDecommissionManager will be introduced that will receive these commands and carry out the decommission steps. In this patch NodeDecommissionManager is only a skeleton implementation to receive the commands as this patch is mainly focused on getting the CLI commands and protobuf messages in place. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
