-----------------------------------
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.
