---------------------------------------
Summary: TestKDiag failing intermittently on Jenkins/Yetus at
login from keytab
Key: HADOOP-14636
URL: https://issues.apache.org/jira/browse/HADOOP-14636
Project: Hadoop Common
Issue Type: Bug
Components: security, test
Affects Versions: 3.0.0-beta1
Reporter: Steve Loughran
Priority: Minor
The test {{TestKDiag}} is failing intermittently on Yetus builds,
{code}
org.apache.hadoop.security.KerberosAuthException: Login failure for user:
[email protected] 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.
