Hello,
We are getting the following regular warnings on our webapps that use
zookeeper front ends for our Solr servers:
*[OUR_PLATFORM] 2018-08-02 09:18:55,622 WARN
[org.apache.zookeeper.ClientCnxn] - <Session 0x164f63092270000 for server
172.16.120.14/172.16.120.14:2281, unexpected error, closing socket
connection and attempting reconnect>
java.lang.NoClassDefFoundError: org/apache/zookeeper/proto/SetWatches
at
org.apache.zookeeper.ClientCnxn$SendThread.primeConnection(ClientCnxn.java:927)
at
org.apache.zookeeper.ClientCnxnSocketNIO.doTransport(ClientCnxnSocketNIO.java:363)
at
org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1144)*
The warnings show up routinely (every second) but we cannot see any issues
with it effecting our searching (solr) activities. I would be grateful for
any ideas what this might be related to and how to address. This is
zookeeper 3.4.10, a three node cluster supporting our pair of solrCloud
server instances. Thanks for any ideas.
