Does providing Zookeeper FQDN with port number solve the multiple connections problem

kgkarthik30
Hi Team,


We have a scenario where we give the Zookeeper FQDN to our Solr Application.

When we use this we are seeing that zookeeper is accepting connections from
all Solr nodes every minute.


When we provide the Zookeeper FQDN with the port number, we are seeing that
there is a single connection created with Solr. Is this something that has
been already seen earlier on.


I have tested it out on my local cluster and identified this issue. Has
anyone seen this issue previously? If yes, please let me know.


I have tested on a cluster with *3 Solr nodes* and *3 Zookeeper nodes*

Logs for one of the Zookeeper nodes

Solr, Number of connections from Zookeeper]*
