Hello,
I am using solr 7.3 and zookeeper 3.4.10. I have custom client code that is
supposed to connect the a zookeeper cluster. For the sake of clarity, the
main code focus:
private synchronized void initSolrClient()
{
List<String> zookeeperList = new ArrayList<String>();
zookeeperList.add("http://100.12.119.10:2281";);
zookeeperList.add("http://100.12.119.10:2282";);
zookeeperList.add("http://100.12.119.10:2283";);
String collectionName = "myCollection"
log.debug("in initSolrClient(), collectionName: " +
collectionName);
try {
solrClient = new CloudSolrClient.Builder(zookeeperList,
null).build();
} catch (Exception e) {
log.info("Exception creating solr client object. ");
e.printStackTrace();
}
solrClient.setDefaultCollection(collectionName);
}
Before executing, I test that all three zoo nodes are running
(./bin/zkServer.sh status zoo.cfg, ./bin/zkServer.sh status zoo2.cfg,
./bin/zkServer.sh status zoo3.cfg). The status shows the quorum is
up and running, with one nodes as the leader and the other two as followers.
When I execute my java client to connect to the zookeeper cluster, I get :
java.lang.NullPointerException
at
org.apache.solr.client.solrj.impl.CloudSolrClient$Builder.<init>(CloudSolrClient.java:1387)
I am assuming it has a problem with my null value for zkChroot, but not
certain. Th API says zkChroot is the path to the root ZooKeeper node
containing Solr data. May be empty if Solr-data is located at the ZooKeeper
root.
I am confused on what exactly should go here, and when it can be null. I
cannot find any coding examples.
Any help greatly appreciated.
