Jeff Jirsa commented on CASSANDRA-13728:
----------------------------------------
I'm not [~jasobrown] , but I do have an opinion that we shouldn't change output
of existing JMX endpoints in minor versions, as people may be parsing it with
tools and relying on its output not changing. We should treat it as a public
API, and not break it on a minor.
Would be better (in my opinion) to use {{spProxy.getMaxHintWindow()}} to add a
new nodetool command (such as {{nodetool handoffwindow}} or similar) instead.
> Provide max hint window as part of nodetool

> Project: Cassandra
> Issue Type: Improvement
> Components: Tools
> Reporter: Milan Milosevic

> 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 nodetool.
> 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.
