Jason Lowe commented on HADOOP-14636:
-------------------------------------

This looks like a dup of HADOOP-14030.

> {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.
