Subject [jira] [Updated] (HADOOP-13674) S3A can provide a more detailed error message when accessing a bucket through an incorrect S3 endpoint.
Date Tue, 04 Oct 2016 05:55:20 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-13674?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chris Nauroth updated HADOOP-13674:
-----------------------------------
    Attachment: HADOOP-13674-branch-2.001.patch

I'm attaching patch 001.  Summary:

* Add specific exception translation logic for an HTTP 301 response.  Include the recommended
S3 endpoint and a hint to check {{fs.s3a.endpoint}} in the exception message.
* Update example error in documentation to show that the error message contains the recommended
endpoint.
* Introduce a new unit test suite, {{TestS3AExceptionTranslation}}.  This consists of tests
refactored out of {{ITestS3AFailureHandling}} that didn't really have a dependency on the
S3 service, a new test for an HTTP 301 response, and several other tests for HTTP status codes
that weren't already covered, like 403, 410 and 416.

> When accessing the S3 service through a region-specific endpoint, the bucket must be
located in that region.  If the client attempts to access a bucket that is not located in
that region, then the service replies with a 301 redirect and the correct region endpoint.
 However, the exception thrown by S3A does not include the correct endpoint.  If we included
that information in the exception, it would make it easier for users to diagnose and fix incorrect
configuration.
