> Currently on the dead nodes page of a namenode, we only list the dead datanode's hostnames.
In addition I would like to list the duration since the node was declared as dead, for example
in the same format as the "Decommissioning Nodes" page when it lists "Time Since Decommissioning
Started".
> In our Hadoop clusters if a node has only been dead for a few minutes, our monitoring
is likely to bring the node back without us needing to do anything about it. This proposed
functionality will help administrators identify which nodes need manual attention and which
nodes are likely to be fixed by our monitoring. If the node has been dead for many hours,
it merits a closer look.
> This seems like useful functionality for open source as well.
