>
> As hadoop operation user, want a host-level Overview Heatmap diagram for
> servers like hadoop nodes like NameNode/DataNode/RegionServer, so that we
> could easily identity healthy/unhealthy overview status of the whole cluster:
> Features:
> 1) HDFS Heatmap (Namenode/DataNode) / HBase HeatMap (HMaster/HRegionServer)
> 2) Use red for unhealthy and green for healthy nodes
> 3) Support to display more detail status/metrics while hovering on certain
> node (we could continuously add highlighted metrics in the detail section)
> 4) Support easily switch from `HeatMap`/`List` view by icon buttons
> 5) We should make sure our diagram compatible and rich information if
> possible instead of separate different information everywhere.
