KMS Hadoop 的身份验证问题

Question

我是 hadoop KMS 的新手，我已经使用 hadoop 启动了 KMS。现在我尝试运行这个 curl 命令

curl -i --header "Accept:application/json" -H "Content-Type:application/json" --user hdfs:hdfs -X GET http://192.168.23.199:16000/kms/v1/keys/names

hdfs 是我的 hadoop 用户并且有 hdfs 密码。

当我运行这个 curl 命令时，我得到以下响应

HTTP/1.1 401 未经授权的服务器：Apache-Coyote/1.1 WWW-Authenticate： PseudoAuth Set-Cookie: hadoop.auth=;过期=星期四，1970 年 1 月 1 日 00:00:00 格林威治标准时间; HttpOnly 内容类型：text/html;charset=utf-8 内容长度：997

这是我的 kms-site.sml 内容

  <!-- KMS Cache -->
<property>
    <name>hadoop.kms.cache.enable</name>
    <value>true</value>
    <description>
      Whether the KMS will act as a cache for the backing KeyProvider.
      When the cache is enabled, operations like getKeyVersion, getMetadata,
      and getCurrentKey will sometimes return cached data without consulting
      the backing KeyProvider. Cached values are flushed when keys are deleted
      or modified.

如果您不使用 kerberos，我通常最终会在 curl 命令中传递用户信息。 卷曲看起来像。

curl -k http://localhost:16000/kms/v1/keys/names?user.name=hdfs
