> After enabling NameNode HA (before doing any page refreshes), the HDFS
> summary page shows Secondary NameNode with the state "Unknown". Also,
> various metrics show up as "n/a".
> I waited a while but this problem did not automatically go away.
> After doing page refresh, everything looked OK.
> As a simple fix, perhaps when we exit NameNode HA wizard, we should force a
> page refresh.
