-------------------------------------------
Summary: UGI renewal thread should be spawn only if the keytaab is
not external
Key: HADOOP-13807
URL: https://issues.apache.org/jira/browse/HADOOP-13807
Project: Hadoop Common
Issue Type: Bug
Components: security
Affects Versions: 3.0.0-alpha1, 2.6.4, 2.7.2
Reporter: Alejandro Abdelnur
Priority: Minor
The renewal thread should not be spawned if the keytab is external.
Because of HADOOP-13805 the can be a case that an UGI does not have a keytab
because authentication is managed by the host program. In such case we should
not spawn the renewal thread.
