Daryn Sharp commented on HDFS-4783:
-----------------------------------
Sigh, this is technically masking an underlying bug of a double fwd/rev resolve
which can return a different hostname and foul the use of CNAMES. Fixing it is
probably more complex than it seems, so +0.5.
> TestDelegationTokensWithHA#testHAUtilClonesDelegationTokens fails on Windows

> Project: Hadoop HDFS
> Issue Type: Bug
> Components: test
> Affects Versions: 3.0.0, 2.1.0-beta
> Reporter: Chris Nauroth

> This test asserts that delegation tokens previously associated to a host with
> a resolved IP address no longer match for selection when
> hadoop.security.token.service.use_ip is set false. The test assumes that
> 127.0.0.1 resolves to host name "localhost". On Windows, this is not the
> case, and instead it resolves to "127.0.0.1".
