Thanks [~manojg] for the useful test cases! We might want to add test cases of putting some nodes to decommission and other nodes to maintenance at the same time. But that can be done in a separate jira unless it is your attention to do it here. > Verify multiple DataNodes can be decommissioned/maintenance at the same time > ---------------------------------------------------------------------------- > > Key: HDFS-11378 > URL: https://issues.apache.org/jira/browse/HDFS-11378 > Project: Hadoop HDFS > Issue Type: Bug > Components: hdfs > Affects Versions: 3.0.0-alpha1 > Reporter: Manoj Govindassamy > Assignee: Manoj Govindassamy > Attachments: HDFS-11378.01.patch > > > DecommissionManager is capable of transitioning multiple DataNodes to Decommission/Maintenance states. Current tests under TestDecommission and TestMaintenanceState only request for one DataNode for Decommission/Maintenance. Better if we can simulate real world cases whereby multiple DataNodes can be taken out of service and verify the resulting block replication factor for the files. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: hdfs-issues-help@hadoop.apache.org
