从Spark访问Openstack Swift - SwiftAuthenticationFailedException

Question

我试图从Spark 2.4访问Openstack Swift但我收到一个错误。

org.apache.hadoop.fs.swift.exceptions.SwiftAuthenticationFailedException: Authenticate as tenant '78axxxxxxxxxxxxxxxxxxxxxxxxxxxx' PasswordCredentials{username='xxxxxxxxxxxx'}

sc.hadoopConfiguration.set(s"fs.swift.service.ovh.auth.url", "https://auth.cloud.ovh.net/v3/")
sc.hadoopConfiguration.set(s"fs.swift.service.ovh.tenant", "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx")
sc.hadoopConfiguration.set(s"fs.swift.service.ovh.username", "xxxxxxxxxxxx")
sc.hadoopConfiguration.set(s"fs.swift.service.ovh.password", "xxxxxxxxxxxxxxxxxxxx")
sc.hadoopConfiguration.set(s"fs.swift.service.ovh.http.port", "8080")
sc.hadoopConfiguration.set(s"fs.swift.service.ovh.region", "BHS3")
sc.hadoopConfiguration.set(s"fs.swift.service.ovh.public", "false")

我相信这些凭据是正确的，因为它们直接来自openstack rc文件，我可以在使用python-swiftclient时使用它们。我也尝试过使用v2.0端点但没有成功。

不幸的是，我总是得到这个非常通用的错误消息，它不会告诉我哪个部分失败了。有没有办法更好地调试这个？

我使用了以下从OVH spark提交团队收到的示例。一个重要的注意事项是使用租户名称而不是openstack.rc文件中的租户ID。

val hadoopConf = spark.sparkContext.hadoopConfiguration

hadoopConf.set("fs.swift.impl","org.apache.hadoop.fs.swift.snative.SwiftNativeFileSystem")
hadoopConf.set("fs.swift.service.auth.endpoint.prefix","/AUTH_")
hadoopConf.set("fs.swift.service.abc.http.port","443")
hadoopConf.set("fs.swift.service.abc.auth.url","https://auth.cloud.ovh.net/v2.0/tokens")
hadoopConf.set("fs.swift.service.abc.tenant","<TENANT NAME> or <PROJECT NAME>")
hadoopConf.set("fs.swift.service.abc.region","<REGION NAME>")
hadoopConf.set("fs.swift.service.abc.useApikey","false")
hadoopConf.set("fs.swift.service.abc.username","<USER NAME>")
hadoopConf.set("fs.swift.service.abc.password","<PASSWORD>")
