During CDCR, after syncing data directories from source to target collection's 
replicas and then starting Target and Source cluster, when I start the CDCR 
replication using /cdcr?action=START on Source collection,

On Source collection, I am getting following error on Solr admin logging 
section:
|BaseCloudSolrClient|Request to collection [search1] failed due to (400) 
org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException: Error 
from server at http://IP:PORT/solr/search1_shard1_replica_n1: ERROR: 
[doc=A_someID_s] multiple values encountered for non multiValued field 
StartDate_dt: [2012-04-12T00:00:01.000Z,​ 
2012-04-12T00:00:01.000Z],​ retry=0 commError=false errorCode=400|

 

and following warning:
|CdcrReplicator|Failed to forward update request to target: search1|

 

Also on Target Collection getting following ERROR :
|ERROR 
false|x:search1_shard1_replica_n1|RequestHandlerBase|org.apache.solr.common.SolrException:
 ERROR: [doc=A_someID_s] multiple values encountered for non multiValued field 
StartDate_dt: [2012-04-12T00:00:01.000Z,​ 2012-04-12T00:00:01.000Z]|

 

The field I am using is :

 

<dynamicField name="*_dt" type="date" indexed="true" stored="true" 
multiValued="false" omitNorms="true"/>

<fieldType name="date" class="solr.TrieDateField" precisionStep="0" 
positionIncrementGap="0"/>

 

 Other CDCR monitoring actions and STAR, STOP and BOOTSTRAP are working fine.
