> Currently there does not seem to be any "clean" way to remove a particular Solr node
from a ZooKeeper collection running in SolrCloud.  I watched the talk at Lucene Revolution
2012 about this area and it seems like the recommended approach at present is to just shut
down the node.  This is problematic for a couple reasons:  one is that it creates a reliance
on the ZK config (how soon will ZK know that the node is gone?) and creates a potentially
bad user experience (how many queries will get sent to the node that was just shut down before
the next tick elapses?).  It also makes it impossible to use the node in an "offline" state
-- for example, if something went wrong on the box it might be good to look at a dump of the
running process, etc. but if it's turned off we can't easily do that.  
> Ideally there could be a series of core commands/primitives that one could issue to any
Solr node to do things like remove a node from a ZK collection, re-connect to a ZK instance,
a particular collection, etc.  It might also be useful to be able to start up a Solr node
without initially connecting to ZK.
> I looked at [SOLR-3488|http://issues.apache.org/jira/browse/SOLR-3488] but that issue
seems more related to managing collections within ZK, not so much about nodes within a particular
collection.  Apologies if these topics are covered there.
