SolrCloud ZooKeeper Configuration updates

How do I update an existing configuration file of SolrCloud in the Zoo Keeper?

I am using Solr4 Beta version with ZooKeeper 3.3.6. I have updated a configuration file, and restarted the Solr Instance which uploads the configuration file to the ZooKeeper. But when I check the configuration file from the SolrCloud Admin console, I don't see the updates. I am not able to understand if this is an issue with SolrCloud admin console or if I am not successful in uploading the config file to ZooKeeper.

Can someone who is familiar with ZooKeeper tell me on how to update an existing configuration file in the ZooKeeper, and how to verify the change in the ZooKeeper?

Did you restart Solr with -Dbootstrap_conf=true option ? – Saurabh Saxena
Yes, the option is true. I had multiple cores defined in the instance and you would have to upload each configuration by changing -Dcollection.configName argument and restart the server every time. – Ravi

Solr 4 comes with some helpful scripts

cloud-scripts/zkcli.sh -cmd upconfig -zkhost 127.0.0.1:2181 -d solr/your_default_collection_with_the_config/conf/ -n config_name_userd_by_all_collections

After that you have to reload cores.

SolrCloud provides two option for uploading configuration files to ZK. If you have multiple cores while starting give option -Dbootstrap_conf=true. This will upload the index configuration files for all the cores. If you only want to upload configuration file of one core give two startup parameters -Dbootstrap_confdir and -Dcollection.configName.
