Mark Miller commented on SOLR-4566:
-----------------------------------

I'm going to nuke this - it's broken and none of the other code expects to only 
get back active shards.
                
> Fix calls to clusterstate#getSlices that should be clusterstate#getAllSlices.

> I'm not sure I really like this getSlices vs getAllSclies - it's kind of easy 
> to get in trouble right now I think. Some spots that we clearly want to call 
> getAllSlices got left with getSlices. It's almost surprising that getSlices 
> only returns active replicas - it should probably at least be called 
> getSlicesWithActive or something more explicit. But for the first step, we 
> should just fix the various mis calls.
> There are a couple problems around the mis calls, the most severe probably 
> being that you can lose shards that are not active from the clusterstate.json 
> given the right races.
