Shalin Shekhar Mangar created SOLR-4797:
-------------------------------------------
Summary: Sub shards have wrong hash range in cluster state except
when using PlainIdRouter
Key: SOLR-4797
URL: https://issues.apache.org/jira/browse/SOLR-4797
Project: Solr
Issue Type: Bug
Components: SolrCloud
Affects Versions: 4.3
Reporter: Shalin Shekhar Mangar
Assignee: Shalin Shekhar Mangar
Fix For: 4.4
The overseer collection processor always uses PlainIdRouter to partition the
hash range. However, some router implementations (most notably
CompositeIdRouter) can provide a different implementation to partition hash
ranges. So there can be a mismatch between the hash ranges which are persisted
in clusterstate.xml for sub shards and the actual index which is split using
the collection's configured router impl.
This bug does not affect collections using PlainIdRouter.
The overseer collection processor should always use the collection's configured
router to partition ranges.
