在对solr进行了几次成功的更新之后,抛出SolrException:java。util。同时发生的TimeoutException:无法连接到ZooKeeper

我正在使用solr版本7.3.1,并将其与3个外部zookeeper节点一起使用。

下面是其中一个节点的zookeeper配置,所有节点都有类似的配置:

tickTime=2000

initLimit=10
syncLimit=5
dataDir=/Users/<user>/zookeeper/zookdata/zk2/
clientPort=2182

server.1=localhost:2666:3666
server.2=localhost:2667:3667
server.3=localhost:2668:3668

然后,我使用这3个节点来启动solr。在我的应用程序中,我使用 localhost:2182,localhost:2183 要连接到solr,请使用以下代码。

List<String> zkHosts = Arrays.asList(solrZkHostPort.split(","));
    CloudSolrClient.Builder builder = new CloudSolrClient.Builder(zkHosts, Optional.empty());
    solrClient = builder.build();

我正在使用多个spark执行器将文档更新为solr。在更新失败后,对于大约1100-1300条记录的更新,它可以正常工作,但以下情况除外:

Caused by: org.apache.solr.common.SolrException: java.util.concurrent.TimeoutException: Could not connect to ZooKeeper localhost:2182,localhost:2183 within 10000 ms

我也得到以下例外,但不确定这是否有任何意义:

18/09/20 12:45:40 WARN ClientCnxn: Session 0x0 for server localhost/127.0.0.1:2183, unexpected error, closing socket connection and attempting reconnect

知道有什么问题吗?我是否需要更改zookeeper配置,或者更改我创建solr客户端的方式?
