SolrCloud and configuration files on ZooKeeper

[mattia.martine...@gmail.com]

Hi.
I setted up a SolrCloud cluster with 3 nodes and configuration files on
Zookeeper.
I read the document at
https://cwiki.apache.org/confluence/display/solr/Using+ZooKeeper+to+Manage+Configuration+Files
and saw that configuration files are stored on ZooKeeper of course.
But now I have to update my custom schema.xml and I cannot realize how I
can download the current config set to update it.
Could you help me please?
Thank you very much!
Bye
