> On a busy cluster, sometimes it takes bit of time for deleted node(from the 
> cluster)'s "slow node report" to get removed from slow peer json report on 
> Namenode JMX metrics. In the meantime, user should be able to browse through 
> more entries in the report by adjusting i.e. reconfiguring 
> "dfs.datanode.max.nodes.to.report" so that the list size can be adjusted 
> without user having to bounce active Namenode just for this purpose.
