Steve Loughran commented on HADOOP-15671:
-----------------------------------------
LGTM; looks very like the AWS version
in {{validateCredential}} test
* recommend use LambdaTestUtils.intercept() for the operation-raising-exception
code.
* if the exception isn't as expected, rather than call fail(), its better to
rethrow the whole exception.That way the failure details aren't lost
ps HADOOP-14556 is exploring using STS for delegation tokens. Keep that in mind
as a future extension.
