> Key: SOLR-6205
> URL: https://issues.apache.org/jira/browse/SOLR-6205
> Project: Solr
> Issue Type: New Feature
> Components: SolrCloud
> Affects Versions: 4.8.1
> Reporter: Arcadius Ahouansou
> Assignee: Noble Paul
> Priority: Major
>
> Use case:
> Let's say we have SolrCloud deployed across 2 Datacenters, racks or zones A and B
> There is a need to have a SolrCloud deployment that will make it possible to have a working system even if one of the Datacenter/rack/zone A or B is lost.
> - This has been discussed on the mailing list at
> http://lucene.472066.n3.nabble.com/SolrCloud-multiple-data-center-support-td4115097.html
> and there are many workarounds that require adding more moving parts to the system.
> - On the above thread, Daniel Collins mentioned https://issues.apache.org/jira/browse/ZOOKEEPER-107
> which could help solve this issue.
> - Note that this is a very important feature that is overlooked most of the time.
> - Note that this feature is available in ElasticSearch.
> See http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/modules-cluster.html#allocation-awareness
