Steve Loughran resolved HADOOP-14636.
-------------------------------------
    Resolution: Duplicate

you are right resolving. Doesn't fix the problem though.

I think maybe we should hava a "yetus" profile where we turn of those tests which fail on the yetus builds but not elsewhere...that way test runs aren't confused by errors that appear to be some local env problem (network, kerberos, ...)

> The test {{TestKDiag}} is failing intermittently on Yetus builds, 
> {code}
> org.apache.hadoop.security.KerberosAuthException: Login failure for user: foo@EXAMPLE.COM from keytab /testptch/hadoop/hadoop-common-project/hadoop-common/target/keytab javax.security.auth.login.LoginException: Unable to obtain password from user
> {code}
> The tests that fail are all trying to log in using a keytab just created, the JVM isn't having any of it.
> Possible causes? I can think of a few to start with
> # keytab generation
> # keytab path parameter wrong
> # JVM isn't doing the login
> # some race condition
> # Host OS
> # Other environment issues (clock, network...)
> There's no recent changes in the kdiag or UGI code.
> The failure is intermittent, not surfacing for me (others?) locally, which which could point at: JVM, host OS, race condition, other env  issues.
