I'm upgrading from solr4.1.0 to solr4.7.1. previously, I deployed SolrCloud(more than 2 nodes) which using an external ZooKeeper ensemble. the solr.xml looks like:
<solr persistent="true" sharedLib="lib">
<cores adminPath="/admin/cores" host="${host:}" hostPort="${jetty.port:}" hostContext="solr">
<core collection="collection1" name="core1" instanceDir="core1" />
</cores>
</solr>
and I bootstrap the cloud by the following command on one node:
java -Djetty.port=8983 -Dsolr.solr.home=/dir/to/mysolrhome -Dbootstrap_conf=true -DzkHost=zookeeper1:2181 -jar start.jar
and use the following command to start other solr nodes:
java -Djetty.port=8983 -Dsolr.solr.home=/dir/to/mysolrhome -DzkHost=zookeeper1:2181 -jar start.jar
my directory structure of solr.home is:
mysolrhome
|--core1
|--solr.xml
everything is going well when using solr4.1.0.
but when I upgrade solr to v4.7.1, I got the follwoing Exception:

I check the zookeeper, it shows the following structure：
it seems the configure directory uploaded to the zookeeper is the core name core1, but solr load the configure directory for collection name collection1.
and when I change solr.xml to set the core name to collection1, it will work.
My question is, can I configure the uploaded config directory for each collection? or if I change my core name, is there any side-effect to my previous application? or arethere any other solutions?
I don't use -Dbootstrap_confdir, because it only support one collection. I have multiple collections with different schema used.
thanks in advance.
