Re: Connection Problem with CloudSolrClient.Builder().build When passing a Zookeeper Addresses and RootParam
Thank you Andy, The problem was as you suspected, the "http://; prefixes. The odd thing is that I used to use the one param constructor with the solr node URL list (like: CloudSolrClient.Builder(solrServerURLLList).build();). I could not get that one to work without the "http://; prefix. Anyway between removing the prefix and using chrootOption = Optional.empty(), my problems are solved. You have literally made my day!

Re: Connection Problem with CloudSolrClient.Builder().build When passing a Zookeeper Addresses and RootParam
>From the error, I think the issue is with your zookeeperList definition.
Try changing:
zookeeperList.add("http://100.12.119.10:2281;);
zookeeperList.add("http://100.12.119.10:2282;);
zookeeperList.add("http://100.12.119.10:2283;);
to
zookeeperList.add("100.12.119.10:2281");
zookeeperList.add("100.12.119.10:2282");
zookeeperList.add("100.12.119.10:2283");
If you are not using a chroot in Zookeeper then just use chrootOption =
Optional.empty(); (as you have done).
Intent of my code was to support both using a chroot and not using a
chroot. The value of _zkChroot is read from a config file in code not shown.

Re: Connection Problem with CloudSolrClient.Builder().build When passing a Zookeeper Addresses and RootParam
Thanks. So I tried what you had, however, you are not specifying _zkChroot,
so I don't know what to put there. I don't know what that value would be for
me, or if I even need it. So I commented out most you example to:
Optional chrootOption = null;
// if (StringUtils.isNotBlank(_zkChroot))
// {
// chrootOption = Optional.of(_zkChroot);
// }
//else
//{
chrootOption = Optional.empty();
by the way which StringUtils API are you using? There are a couple that have
that isNotBlank.
In any event, I have now getting a different exception when trying to create
the client:
ERROR [] -
java.lang.RuntimeException: Error committing document

So, perhaps I need the root specified (since it say "caused by empty node

Thanks for any insights.

Re: Connection Problem with CloudSolrClient.Builder().build When passing a Zookeeper Addresses and RootParam
Hi,
Yes, Andy has the right idea. If no zk-chroot is being used,
"Optional.empty()" is the correct value to specify, not null.
This API is a bit trappy (or at least unintuitive), and we're in the
process of hashing out some doc improvements (and/or API changes). If
you're curious or would otherwise like to weigh in, check out SOLR-12309.
Best,
Jason

Re: Connection Problem with CloudSolrClient.Builder().build When passing a Zookeeper Addresses and RootParam
I am using the following (Solr 7.3.1) successfully:
import java.util.Optional;
Optional chrootOption = null;
if (StringUtils.isNotBlank(_zkChroot))
{
chrootOption = Optional.of(_zkChroot);
}
else
{
chrootOption = Optional.empty();
}
CloudSolrClient client = new CloudSolrClient.Builder(_zkHostList,
chrootOption).build();
Adapted from code I found somewhere (unit test?). Intent is to support the
option of configuring a chroot or not (stored in "_zkChroot")

Connection Problem with CloudSolrClient.Builder().build When passing a Zookeeper Addresses and RootParam
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 zookeeperList = new ArrayList();
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.(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.
