Question

我正在尝试将ignite集成到我的Spark结构化流应用程序中。
以下是我为ignite包含的依赖项
-点火芯，
-点燃火花，
-点燃弹簧，
-缓存API

用于触发的火花配置

private static final String CONFIG = "C:\\apache-ignite-2.7.6-bin\\config\\default-config.xml";
spark.read().format(IgniteDataFrameSettings.FORMAT_IGNITE())
.option(IgniteDataFrameSettings.OPTION_CONFIG_FILE(), CONFIG)
.option(IgniteDataFrameSettings.OPTION_TABLE(), "person")
.load();

完全不知道如何解决以下错误，因为该配置是二进制文件中提供的默认配置。包括所有依赖项。
-点燃2.7.6
-Spark 2.4.0

Answer 1

请查看此线程。看起来那里的人有同样的问题：

Cannot find the declaration of element 'beans'

我想您应该在XML旁边添加

<beans xmlns="http://www.springframework.org/schema/beans" 
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="
    http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans-**[MAYOR.MINOR]**.xsd"

[MAYOR.MINOR]是您的Spring的版本，例如3.1、4.0等。

Answer 2

还应该评论说，尚不支持Spark 2.4。

这是Apache Ignite JIRA上的票证，您可以在此处https://issues.apache.org/jira/browse/IGNITE-12054
