Question

我遇到了这个问题。我知道这个班级在hadoop auth中。我试过2.2和2.6版本。但仍然存在错误。但我看不到它。

我收到了这个错误： -

您缺少此依赖项：

    <dependency>
        <groupId>org.apache.hadoop</groupId>
        <artifactId>hadoop-auth</artifactId>
        <version>${your.hadoop.version}</version>
        <scope>test</scope>
    </dependency>

java.lang.ClassNotFoundException：org.apache.hadoop.security.authentication.server.CookieSignatureSecretFactory
