我尝试连接到我的Cassandra但我可能错误地配置了.我在localhost上运行它.Cassandra已经生成了认证和添加.在cqlsh中,flag -ssl没有错误.我的片段代码是

var tls = require('tls');
var fs = require('fs');
var options = {
	key : fs.readFileSync('client-key.pem'),
	cert : fs.readFileSync('client-cert.pem'),
	ca : [fs.readFileSync('server-cert.pem')]
};
var client = new cassandra.Client({
		contactPoints : ['127.0.0.1'],
		authProvider : new cassandra.auth.PlainTextAuthProvider('cassandra', 'cassandra'),
		sslOptions : tls.connect(options)
	});

我做错了什么？请帮忙!

我有app1.war和app2.war部署在同一个tomcat jvm中.这两个应用程序都有自己的上下文xmls - app1.xml和app2.xml.这两个应用程序都包含连接到Cassandra的数据存储驱动程序依赖项.它们在单独部署时运行良好.但是当两者都部署在同一个jvm中时,我在日志中看到了以下JMX异常:

例如，

 for(..){
     ses.executeAsync(statement);
 }
 ses.close();

驱动程序会在所有请求发出之前关闭吗？
