Nanda kumar commented on HDDS-1953: ----------------------------------- Thanks [~Sammi] for reporting the issue. The set of datanodes in a pipeline (OPEN) cannot change, but the datanode properties (ip/hostname/ports) can change. It is good to update them whenever there is a register/re-register of datanode in SCM. > Remove pipeline persistent in SCM > --------------------------------- > > Key: HDDS-1953 > URL: https://issues.apache.org/jira/browse/HDDS-1953 > Project: Hadoop Distributed Data Store > Issue Type: Improvement > Reporter: Sammi Chen > Assignee: Sammi Chen > Priority: Major > > Currently, SCM will persistent pipeline in metastore with datanode > information locally. After SCM restart, it will reload all the pipelines from > the metastore. If there is any datanode information change during the whole > SCMc lifecycle, the persisted pipeline is not updated. -- This message was sent by Atlassian JIRA (v7.6.14#76016) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
