Subject [jira] [Commented] (HADOOP-12537) s3a: Add flag for session ID to allow Amazon STS temporary credentials
Date Wed, 01 Jun 2016 22:42:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12537?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15311279#comment-15311279

Sean Mackrory commented on HADOOP-12537:
----------------------------------------

It looks to me like you can append to the session token and it will still work - it must just
be parsing what it expects and not looking at the rest. I can make the test fail by prepending,
or simply setting the empty string as the session token. As soon as I append to an otherwise
valid session token, the test fails because the S3 access still works.

I thought I also observed behavior where authorization seemed to be cached for a short period
of time, but I have been misinterpreting the behavior I just described. Going to run through
a few more tweaks of the test case to ensure this is not the case.

> Amazon STS allows you to issue temporary access key id / secret key pairs for your a
user / role. However, using these credentials also requires specifying a session ID. There
is currently no such configuration property or the required code to pass it through to the
API (at least not that I can find) in any of the S3 connectors.
