Solr on Several Machines Communication Fails

[Ophir Michaeli]

Hi,

I' running Solr on 4 machines with the following configuration:
Solr Vesrion: 4.3
Solr Cloud

Machine 1: 
running shard 1 with embedded zokeeper -
java -Dbootstrap_confdir=./solr/collection1/conf
-Dcollection.configName=myconf -DzkRun -DnumShards=2 -jar start.jar

Machine 2:
Running shard 2
java -Djetty.port=7574 -DzkHost=shard1_Machine_IP:9983 -jar start.jar

Error:

ERROR - 2013-06-27 15:18:06.066; org.apache.solr.common.SolrException;

If I run the same 2 shards on one machine it works, I get  correct response
for queries.

Thanks
