【问题描述】：
我正在使用 Apache Ignite .Net v2.7。在解决另一个问题 (How to use TcpDiscoveryKubernetesIpFinder in Apache Ignite .Net) 时，我添加了一个 sprint 配置文件，其中指定了 Kubernetes 配置。所有其他配置都在 C# 代码中。
配置文件的内容如下（取自文档）：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util.xsd">
<bean class="org.apache.ignite.configuration.IgniteConfiguration">
<property name="discoverySpi">
<bean class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi">
<property name="ipFinder">
<bean class="org.apache.ignite.spi.discovery.tcp.ipfinder.kubernetes.TcpDiscoveryKubernetesIpFinder">
<property name="namespace" value="ignite"/>
</bean>
</property>
</bean>
</property>
</bean>
</beans>
引用该文件的C#代码如下：
var igniteConfig = new IgniteConfiguration
{
SpringConfigUrl = "./kubernetes.config",
JvmClasspath = string.Join(";",
new string[] {
"ignite-kubernetes-2.7.0.jar",
"jackson-core-2.9.6.jar",
"jackson-databind-2.9.6.jar"
}
.Select(c => System.IO.Path.Combine(Environment.CurrentDirectory, "Libs", c)))}
Ignite 节点在本地启动正常，但在部署到 Kubernetes 集群时，它失败并出现以下错误：

您知道为什么会发生这种情况吗？它在抱怨哪个记录器？
Kubernetes 正在运行 Linux 容器，我在本地使用的是 Windows 10。
另外两个观察：
当我将配置文件名指定为
kubernetes.config时，节点在本地成功启动，但在 Kubernetes 中失败并出现错误，提示 URL“kubernetes.config”缺少架构部分。JvmClasspath：我必须添加“ignite-kubernetes-2.7.0.jar”，否则找不到 JAR，尽管它与其他 Ignite 类位于同一目录中。添加接下来的两个条目没有任何区别。
