Project: Hadoop Common
Issue Type: Bug
Components: kms
Affects Versions: 2.7.0
Reporter: Sangjin Lee
Assignee: Sangjin Lee
On some platforms all unit tests that use minikdc fail consistently. Those
tests include TestKMS, TestSaslDataTransfer, TestTimelineAuthenticationFilter,
etc.
Typical failures on the unit tests:

reply)
