Switching to using SolrCloud with tomcat7 and embedded zookeeper

I am running solr 4.3 with tomcat 7 (with non SolrCloud) and have 4 solr
cores running. 

Switching to start using SolrCloud with tomcat7 and embedded zookeeper I
updated JAVA_OPTS in this file tomcat7/bin/setenv.sh to following,

JAVA_OPTS="-Djava.awt.headless=true -Xms2048m -Xmx4096m
-XX:+UseConcMarkSweepGC -Dbootstrap_confdir=/<path>/solr/collection1/conf/
-Dcollection.configName=collection1_conf -DnumShards=1 -DzkRun"

Now, all my cores (collections) are set to the default collection1 schema. 
Not sure why?

solr.xml is set to correct instanceDir settings.

Any pointers?
Thanks, 
-Manasi

If you are not defining global Java startup parameters do not include them
at setenv.sh. Pass that arguments as parameters when you startup your jar.

Re: Switching to using SolrCloud with tomcat7 and embedded zookeeper

Originally i was running a single solr 4.3 instance with 4 cores ... and now
starting to learn about solrCloud and thought I could setup number of
shards=1 (since its a single instance) and same 4 cores can be converted to
4 collections on the same single shard same single instance. 

How do I define each -Dcollection.configName as a part of setenv.sh?
should I point my -Dbootstrap_confdir to parent directory instead?

You've specified bootstrap_confdir and the same collection.configName on
all your cores, so as each of them start, each will be uploading its own
configuration to the collection1_conf area of ZK, so they will all be
overwriting each other.

Are your 4 cores replicas of the same collection or are they distinct
collections?  If the latter, then why put them all in SolrCloud (there
really isn't any benefit?) but assuming you wanted to do it for expansion
reasons (to add replicas later on), then each one will need to have a
distinct collection.configName parameter, so that ZK knows to keep the
configs separate.
