> Key: SOLR-7271
> URL: https://issues.apache.org/jira/browse/SOLR-7271
> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Affects Versions: 4.5
> Reporter: Gregory Chanan
> Assignee: Gregory Chanan
> Fix For: 4.10.5
>
> Attachments: SOLR-7271.patch, SOLR-7271ClusterState.patch

> SOLR-4221 changed the router format from e.g.:
> {code}
> ...
> "router":"compositeId”,
> ...
> {code}
> to:
> {code}
> ...
> "router":{"name":"compositeId"},
> ...
> {code}
> This later commit: https://github.com/apache/lucene-solr/commit/54a94eedfd5651bb088e8cbd132393b771f5f5c2 added backwards compatibility in the sense that the server can read the old router format. But the old 4.4 client can't read the new format, e.g. you get:
> {code}
