I looked at SolrCloudTestCase to see how MiniSolrCloudCluster should be
used, then I wrote a little program and configured ivy to pull down
solr-test-framework from 6.0.0 (getting ivy to work right was an
adventure!). Based on what I found in SolrCloudTestCase, this is the
code I wrote last evening:
public class MiniSC
{
static JettyConfig jettyConfig = null;
static MiniSolrCloudCluster msc = null;
static CloudSolrClient client = null;
public static void main(String[] args) throws Exception
{
jettyConfig = JettyConfig.builder().setContext("/solr").build();
msc = new MiniSolrCloudCluster(2, Paths.get("testcluster"),
jettyConfig);
client = msc.getSolrClient();
client.close();
msc.shutdown();
}
}
At first, I saw the same exception you got ... but after a little while
I figured out that this is because I was running the program more than
once without deleting everything in the baseDir -- so the zookeeper
server was starting with an existing database already containing the
solr.xml. When MiniSolrCloudCluster is used in Solr tests, the baseDir
is newly created for each test class, so this doesn't happen.
When I delete everything in "testcluster" and run my test code, I get
the following in my logfile:
http://apaste.info/Dkw
There are no errors, only WARN and INFO logs. At this point, I should
be able to use the client object to upload a config to zookeeper, create
a collection, and do other testing.
Thanks,
