---------------------------------
    Attachment: SOLR-6481.patch

Here's a patch that cross-checks the replica state with live nodes. Since the code just uses the /clusterstate.json JSON map directly, I took the approach of walking the tree to check replica status.

> CLUSTERSTATUS action reports the state of replicas but it doesn't check /live_nodes, which means it might show a replica as "active" but the node is down, so the real state is "down".
> Ideally, we need a helper method that gets replica status that consults live nodes so this error doesn't keep cropping up all over the code base.
