-------------------------------
Summary: Unclear error message during recovery
Key: SOLR-8275
URL: https://issues.apache.org/jira/browse/SOLR-8275
Project: Solr
Issue Type: Bug
Components: SolrCloud
Affects Versions: 4.10.3
Reporter: Mike Drob
A SolrCloud install got into a bad state (mostly around LeaderElection, I
think) and during recovery one of the nodes was giving me this message:
{noformat}
2015-11-09 13:00:56,158 ERROR org.apache.solr.cloud.RecoveryStrategy: Error

The crux of this message: "I was asked to wait on state recovering for shard1
in c1 on node2:8983_solr but I still do not see the requested state. I see
state: recovering" seems contradictory. At a minimum, we should improve this
error, but there might also be some erroneous logic going on.
