Steve Loughran commented on HADOOP-17641:
-----------------------------------------
I've got the PR merged in with a UUID in name. So it verifies that DNS
resolution takes place and the failure is mapped to IllegalArgumentException.
If someone makes up an account with the UUID, well, it'd take maliciousness to
do it now
> ITestWasbUriAndConfiguration.testCanonicalServiceName() failing now
> mockaccount exists

> The test ITestWasbUriAndConfiguration.testCanonicalServiceName() is failing
> in its intercept
> [ERROR] ITestWasbUriAndConfiguration.testCanonicalServiceName:656 Expected
