Solr dynamic reconfiguration of zookeeper ensemble
Hi All,
We are using solr 8.11.1 with zk 3.2. Recently we have upgraded zk to 3.7.1.
We observe below warning on solr-ui .
"Solr ZK connection string (2 hosts) is different from the dynamic ensemble
config (3 hosts)."
Please let us know will it cause any issue and
Is there any option to make solr support the zk's dynamic reconfiguration .
Thanks in advance.

Hi HariBabu,
Typically a minor version upgrade is safe, but only someone truly
familiar with your system can give you a solid answer to that question. You
and/or your team may find the list of changes helpful in making that
assessment:

Hi Jan,
Is it wise to upgrade solr in PROD to 8.11.2 from 8.11.1 only for that
zookeeper error ?
What are your thoughts?

Hi,
This will not cause any issues. You should however configure all three ZK hosts in your ZK_HOST setting for Solr.
Beware that Solr's connecton to Zookeeper does NOT support dynamic configuration as provided by Zookeeper, i.e. if you e.g. want to resize your ZK cluster you will still have to edit ZK_HOST and restart your Solr cluster, Solr will not pick up the changes from dynamic reconfig.
As for your "SockerException", it is also harmless as it is only affecting the UI, but it will be solved by upgrading to Solr 8.11.2, see https://issues.apache.org/jira/browse/SOLR-15849
