             Summary: Create minimal solrcloud example directory
                 Key: SOLR-5434
                 URL: https://issues.apache.org/jira/browse/SOLR-5434
             Project: Solr
          Issue Type: Improvement
            Reporter: Alan Woodward
            Assignee: Alan Woodward
            Priority: Minor
             Fix For: 4.6, 5.0


The various "intro to solr cloud" pages (for example https://cwiki.apache.org/confluence/display/solr/Getting+Started+with+SolrCloud) currently tell new users to use the example/ directory as a basis for setting up new cloud instances.  These directories contain, under the default solr/ solr home directory, a single core, defined to point to the collection1 collection.

It's not at all obvious that, to change the name of your collection, you have to go and edit the core.properties file underneath the solr/ directory.  A lot of users on the mailing list also seem to get confused by having to include bootstrap_confdir and numShards the first time they run solr, but not afterwards.  So here's a suggestion:

* Have a new solrcloud/ directory in the example webapp that just contains a solr.xml file
* Change the startup example code to just include -Dsolr.solr.home and -DzkRun
* Tell the user to then run zkcli to bootstrap their configuration (solr startup and configuration loading are kept separate)
* Tell the users to use the collections API to create a new collection, naming it however they want (confignames, collection names and core names are all kept separate)

This way, there's a lot less 'magic' and hidden defaults involved, and all the steps to get a cloud up and running (start processes, upload configuration, create collection) are made distinguishable.
