redis - 如何通过redis的接口(interface)连接apache ignite

Question

我想通过redis的接口(interface)从nodejs连接apache ignite在 ignite 配置中，我在 config-default.xml 中添加了下面的 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 64位测试平台)

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]

当测试 nodejs 代码时，例如:

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中得到一个错误信息

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

AbortError

以及 ignite 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。

恐怕您的客户端使用了 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？注意后者有二进制和文本两种形式，只支持其中一种。
