We are using Solrj 10.10.0 to connect to a Zookeeper Solr host. What is the correct pattern for making concurrent requests to the Zookeeper host?
We are currently using CloudSolrServer, but it looks like this class is not thread-safe (setDefaultCollection). Should this instance be initialized once (at startup) and then re-used (in all threads) until shutdown when the process terminates? Or should it re-instantiated for each request? Currently, we are trying to use CloudSolrServer as a singleton, but it looks like the connections to the host are not being closed and under load we start getting failures. and In the Zookeeper logs we see this error: I > WARN - 2014-12-04 10:09:14.364; > org.apache.zookeeper.server.NIOServerCnxnFactory; Too many connections from > /11.22.33.44 - max is 60 > netstat (on the Zookeeper host) shows that the connections are not being closed. What is the 'correct' way to fix this? Apologies if i have missed any documentation that explains, pointers would be helpful. Thanks,
