-----------------------------------------
Summary: 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
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.
