> 1. When  NameNode JMX was not available, HDFS Dashboard is showing "0 live / 0 dead / 0 decommissioned" for "DataNode Status".
> If NameNode JMX was not available, this should show "DataNode Status: n/a"
> 2. Also, NFS Gateway messed up the template.
> Can we fix it so that DataNode Status displays directly underneath "DataNodes", like this:
> DataNodes: xxx
> DataNode Status: xxx
> JournalNodes: xxx
> NFS Gateways: xxx
