Subject [jira] [Commented] (HADOOP-15572) Test S3Guard ops with assumed roles & verify required permissions
Date Mon, 09 Jul 2018 19:53:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-15572?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16537476#comment-16537476
] 

Steve Loughran commented on HADOOP-15572:
-----------------------------------------

What does fail is {{.ITestAssumeRole.testAssumeRoleRestrictedPolicyFS() }}, because with s3:Get*
blocked,initialize() will fail.

Need to consider what tests should do here: add the get Permission or expect it to fail faster
with S3Guard (and assume that?)

>          Issue Type: Sub-task
>          Components: fs/s3

>            Reporter: Steve Loughran
>            Priority: Major
>
> We haven't documented permissions for S3Guard (WiP of mine); when I try to test using
the AssumedRoleCredentialProvider & a role nominally restricted to R/W of S3guard *but
not create/delete*, I can still create and destroy buckets
> Either I've got my list wrong, or how S3Guard sets up its auth isn't right & somehow
falling back to the full role
