> Currently it is not possible to get max_hint_window over nodetool. The information is
available through StorageProxyMBean, though. Since max hint window information is needed in
order to asses what kind of failure recovery should be performed for a node that goes down
(bootstrap or just restart), it would be handy if max hint window is easily accessible using
> Currently nodetool statushandoff output is:
> {code}
> [centos@cassandra-node]$ nodetool statushandoff
> Hinted handoff is running
> {code}
> The output could be improved to look like this:
> {code}
> [centos@cassandra-node]$ nodetool statushandoff
> Hinted handoff is running with max hint window (ms): 10800000
> {code}
> Implementation is quite trivial (fetch the info from the StorageProxyMBean from the StatusHandoff
class). I can provide the patch for this, if it is agreed that this it right approach.
