Question

我想通过redis的接口从nodejs点燃连接apache 在点燃配置中，我在config-default.xml中添加了以下xml定义：

<property name="connectorConfiguration">
    <bean class="org.apache.ignite.configuration.ConnectorConfiguration">
        <property name="host" value="localhost"/>
        <property name="port" value="6379"/>
    </bean>
</property>

并运行ignite.bat（win7 64bit中的测试平台）

console message seeming running fine:
[15:59:09] To start Console Management & Monitoring run ignitevisorcmd.{sh|bat}
[15:59:09]
[15:59:09] Ignite node started OK (id=b58f9f35)
[15:59:09] Topology snapshot [ver=1, servers=1, clients=0, CPUs=4, heap=1.0GB]

测试nodejs代码时如：

var redis = require("redis");
var client = redis.createClient({detect_buffers: true}); 
client.get("test", function (err, reply) {
    if(err == null){
        console.log('reply:'+reply);
    }
    else{
        console.log('error:'+err);
    }
});
client.quit();

在nodejs中收到错误消息

vents.js:183
      throw er; // Unhandled 'error' event
      ^
AbortError: Ready check failed: Stream connection ended and command aborted. It might have been processed.

和点燃控制台中的错误：

我需要帮助才能知道发生了什么？以及如何修复此错误，谢谢。

Answer 1

我担心您的客户端使用Apache Ignite未实现的命令INFO。是否可以尝试替代客户端或memcached客户端？请注意，后者具有二进制和文本形式，只支持其中一种形式。

Answer 2

node.js redis客户端遇到了同样的问题。.的确，Apache Ignite不支持INFO操作，节点redis客户端使用它来检查Redis是否准备好服务查询。它关闭：

redis.createClient({no_ready_check: true});

如何通过redis的界面连接apache点燃
