Hi,
We are experimenting an issue related to Zk Timeout
Stacktrace is :
ERROR 19 juin 2018 06:24:07,152 - h.concurrent.ConcurrentService:67 -

...
In solr.xml, we have :
<int name="zkClientTimeout">${zkClientTimeout:30000}</int>
In Solr.in.sh, we have :
#ZK_CLIENT_TIMEOUT="15000"
or
ZK_CLIENT_TIMEOUT="30000"
So zkClientTimeout should be 30000.
In source code of ZkClientClusterStateProvider.java, I see zkClientTimeout
is hardcoded to 10000 ! Is it normal that configuration is not used ?
lucene-solr/solr/solrj/src/java/org/apache/solr/client/solrj/impl/ZkClientClusterStateProvider.java
int zkConnectTimeout = 10000;
int zkClientTimeout = 10000;
...
zk = new ZkStateReader(zkHost, zkClientTimeout, zkConnectTimeout);
Regards.
Dominique
