> Key: SOLR-4433
> URL: https://issues.apache.org/jira/browse/SOLR-4433
> Project: Solr
> Issue Type: Improvement
> Components: SolrCloud
> Affects Versions: 4.1
> Reporter: Mark Bennett
> Fix For: 4.8
>
>
> When setting up SolrCloud, we have the admin make a copy of example directory
> into the shard template.
> But we issue the warning "Make sure there are no documents present"
> Doc reference:
> http://lucidworks.lucidimagination.com/display/solr/Getting+Started+with+SolrCloud
> Red box: "... On the other hand, make sure also that there are no documents
> in the example directory before making copies."
> We don't say what happens if the data directory is not empty? If this is
> really bad, then I'm not sure if we should just automatically nuke it, or
> prompt them, or give a warning and exit, or maybe a command line switch, OR
> maybe just move it out of the way, maybe renaming it to something with a
> ".NON-CLOUD-INDEX".
> There should be an opportunity to do this. When SolrCloud initializes a new
> shard node, I believe it knows that this is the first time (based on whether
> ZooKeeper has persisted this node's shard assignment, etc.)
