While indexing, several clients have encountered an error like this one:
org.apache.solr.common.SolrException: Solr instance is not running in SolrCloud mode.
The key is this phrase:
Solr instance is not running in SolrCloud mode.This message means that this is a Master/Slave architecture, which is not what Solr Cloud expects to see.
To confirm the Master/Slave architecture, look on the Deployment Details screen.
The error is harmless and can be ignored.
