Unfortunately, the errors can be a bit vague for S3 HeadObject (used by
getFileStatus). There was a similar issue when the credentials had expired in
HADOOP-18353.
```
...
Authorization: AWS4-HMAC-SHA256
Credential=<redacted>/20220823/us-east-1/s3/aws4_request
...
```
The signature is signed for us-east-1, but the `landsat-pds` bucket is in
us-west-2. Do you have `fs.s3a.endpoint.region` set? If so, try adding the
following to your _auth-keys.xml_:
```
<property>
<name>fs.s3a.bucket.landsat-pds.endpoint.region</name>
<value>us-west-2</value>
</property>
```
> AWS AssumedRoleCredentialProvider needs ExternalId add
> ------------------------------------------------------
>
> Key: HADOOP-16806
> URL: https://issues.apache.org/jira/browse/HADOOP-16806
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.2.1
> Reporter: Jon Hartlaub
> Priority: Minor
> Labels: pull-request-available
>
> AWS has added a security feature to the assume-role function in the form of
> the "ExternalId" key in the AWS Java SDK
> {{STSAssumeRoleSessionCredentialsProvider.Builder}} class. To support this
> security feature, the hadoop aws {{AssumedRoleCredentialProvider}} needs a
> patch to include this value from the configuration as well as an added
> Constant to the {{org.apache.hadoop.fs.s3a.Constants}} file.
> The ExternalId is not a required security feature, it is an augmentation of
> the current assume role configuration.
> Proposed:
> * Get the assume-role ExternalId token from the configuration for the
> configuration key {{fs.s3a.assumed.role.externalid}}
> * Use the configured ExternalId value in the
> {{STSAssumeRoleSessionCredentialsProvider.Builder}}
> e.g.
> {{if (StringUtils.isNotEmpty(externalId)) {}}
> {{ builder.withExternalId(externalId); // include the token for
> cross-account assume role}}
> {{}}}
> Tests:
> * +Unit test+ which verifies the ExternalId state value of the
> {{AssumedRoleCredentialProvider}} is consistent with the configured value -
> either empty or populated
> * Question: not sure about how to write the +integration test+ for this
> feature. We have an account configured for this use-case that verifies this
> feature but I don't have much context on the Hadoop project AWS S3
> integration tests, perhaps a pointer could help.
