Gregory Chanan created SOLR-7271:
------------------------------------
Summary: 4.4 client to 4.5+ server compatibility Issue due to
DocRouter format
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
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}
