Hi [~epugh] ,

I have not reproduced the issue you reported. However, I've implemented a check 
to verify if the 'collectionsList' is empty in any case as part of  [GitHub 
Pull Request #2392|https://github.com/apache/solr/pull/2392]. Please let me 
know.

> CloudSolrClient should not throw "Collection not found" with an out-dated

> Today, CloudSolrClient will locally fail if it's asked to send a request to a 
> collection that it thinks does not exist due to its local ClusterState view 
> being out-of-date.  We shouldn't fail!  And most SolrCloud tests should then 
> remove their waitForState calls that follow collection creation!  Other stale 
> state matters are out-of-scope.
> Proposal: CloudSolrClient shouldn't try and be too smart.  Always route a 
> request to Solr (any node); don't presume its state is up-to-date.  Maybe, 
> after a response is received, it can check if its state has been updated and 
> if not then explicitly get a new state.  Or not if that's too complicated.
