Vinayakumar B commented on HDFS-7117:
-------------------------------------
There could be one possibility.
Are you seeing non-zero Decommissioned nodes count next to live nodes count in
overview tab?
"Live Nodes" tab only shows non-decommissioned nodes where as "overview" tab
includes this count in total Live nodes and displays decommissioned nodes count
among these live nodes.
Other than this possibility I am not seeing any other code change related to
this.
Feel free to re-open if you face the issue again,( with screen shots if
possible)
Thanks

> Project: Hadoop HDFS
> Issue Type: Bug
> Components: namenode
> Reporter: Jean-Baptiste Onofré
>
> On a single machine, I have three "fake nodes" (each node use different
> dfs.datanode.address, dfs.datanode.ipc.address, dfs.datanode.http.address)
> - node1 starts the namenode and a datanode
> - node2 starts a datanode
> - node3 starts a datanode
> In the namenode http console, on the overview, I can see 3 live nodes:
> {code}
> http://localhost:50070/dfshealth.html#tab-overview
> {code}
> but, when clicking on the "Live Nodes":
> {code}
> http://localhost:50070/dfshealth.html#tab-datanode
> {code}
> I can see only one node row.
