Steven Bower commented on SOLR-5806:
------------------------------------

Would be a valuable API to have for both external cases like what is described and for the
nodes themselves to decide they should go offline

> In cases of partial failure where a node is still connected to ZooKeeper but failing
-- e.g. bad disk, bad memory, etc. -- it would be nice to have a quick UI link or command-line
script to remove the node from clusterstate.json quickly.
> We've had partial failures where we couldn't SSH into the box but the VM was still running
and connected to ZooKeeper. In these cases, we've had to power the machine down from the [ILO|http://en.wikipedia.org/wiki/HP_Integrated_Lights-Out]
in order to get it out of clusterstate.json. 
> Having something handier in such outages would be great.
