Solr node 'Gone' status
Hi,
Solr-admin cloud view page has got another new radio button indicating
status of node : 'Gone' status. What does that mean? One of my collection
is in that state and it is not serving any request. How to bring that up?

The other possibility is that the "live_nodes" znode
somehow lost the registration of that node. This
shouldn't be happening, I've only seen it when Zookeeper
had problems (full disk in this case).
A node is only considered _really_ available if its
state in the state.json (or clusterstate.json in older
setups) is "active" _and_ it is in the live_nodes
znode.
In this state, the only real cure I know of is to restart
the Solr instance, that'll re-insert itself in the live_nodes
znode.
Best,
Erick

Like Binoy said, It may be because the process/host is down, but also could
be a result of a network problem.

In my experience 'Gone' indicates that that particular solr instance itself
is down.
To bring it back up, simply restart solr.
