-----------------------------------------
Summary: Extend visualization for Maintenance Mode under Datanode
tab in the NameNode UI
Key: HDFS-11265
URL: https://issues.apache.org/jira/browse/HDFS-11265
Project: Hadoop HDFS
Issue Type: Sub-task
Affects Versions: 3.0.0-alpha1
Reporter: Manoj Govindassamy
With HDFS-9391, DataNodes in MaintenanceModes states are shown under DataNode
page in NameNode UI, but they are lacking icon visualization like the ones
shown for other node states. Need to extend the icon visualization to cover
Maintenance Mode.
