Steve Loughran created HADOOP-12833:
---------------------------------------
Summary: KDiag to look at HADOOP_TOKEN_FILE_LOCATION more
Key: HADOOP-12833
URL: https://issues.apache.org/jira/browse/HADOOP-12833
Project: Hadoop Common
Issue Type: Sub-task
Reporter: Steve Loughran
rather than just print {{HADOOP_TOKEN_FILE_LOCATION}}, KDiag could
# fail if its defined and not present (UGI does this meaningfully in 2.8+)
# fail if it is empty
# try to read the credentials direct and review them
Testable
